uni
queries the Unicode database from the commandline. It supports Unicode
14.0 (September 2021) and has good support for emojis.
There are four commands: identify
codepoints in a string, search
for
codepoints, print
codepoints by class, block, or range, and emoji
to find
emojis.
There are binaries on the releases page, and packages for a number of platforms. You can also run it in your browser.
Compile from source with:
$ git clone https://github.com/arp242/uni
$ cd uni
$ go build
which will give you a uni
binary.
README index:
-
dmenu, rofi, and fzf script at
dmenu-uni
. See the top of the script for some options you may want to frob with. -
For a Vim command see
uni.vim
; just copy/paste it in your vimrc.
Note: the alignment is slightly off for some entries due to the way GitHub renders wide characters; in terminals it should be aligned correctly.
Identify characters in a string, as a kind of a unicode-aware hexdump
:
$ uni identify €

'€' U 20AC 8364 e2 82 ac € EURO SIGN (Currency_Symbol)
i
is a shortcut for identify
:
$ uni i h€ý
CPoint Dec UTF8 HTML Name (Cat)
'h' U 0068 104 68 h LATIN SMALL LETTER H (Lowercase_Letter)
'€' U 20AC 8364 e2 82 ac € EURO SIGN (Currency_Symbol)
'ý' U 00FD 253 c3 bd ý LATIN SMALL LETTER Y WITH ACUTE (Lowercase_Letter)
It reads from stdin:
$ head -c2 README.markdown | uni i
cpoint dec utf-8 html name (cat)
'[' U 005B 91 5b [ LEFT SQUARE BRACKET (Open_Punctuation)
'!' U 0021 33 21 ! EXCLAMATION MARK (Other_Punctuation)
You can use -compact
(or -c
) to suppress the header, and -format
(or -f
)
to control the output format, for example you may want to generate a codepoint
to X11 keysym mapping:
$ uni i -c -f '0x%(hex): "%(keysym)", // %(name)' h€ý
0x68: "h", // LATIN SMALL LETTER H
0x20ac: "EuroSign", // EURO SIGN
0xfd: "yacute", // LATIN SMALL LETTER Y WITH ACUTE
See uni help
for more details on the -format
flag; this flag can also be
added to other commands.

The emoji
command (shortcut: e
) is is the real reason I wrote this:
$ uni e cry
Name (Cldr)
🥹 face holding back tears (angry, cry, proud, resist, sad)
😢 crying face (sad, tear)
😭 loudly crying face (sad, sob, tear)
😿 crying cat (face, sad, tear)
🔮 crystal ball (fairy tale, fantasy, fortune, tool)
By default both the name and CLDR data are searched; the CLDR data is a list of
keywords for an emoji; prefix with name:
or n:
to search on the name only:
$ uni e smile
Name (Cldr)
😃 grinning face with big eyes (mouth, open, smile)
😄 grinning face with smiling eyes (mouth, open, smile)
…
$ uni e name:smile
Name (Cldr)
😼 cat with wry smile (face, ironic)
As you can see, the CLDR is pretty useful, as "smile" only gives one result as most emojis use "smiling".
Prefix with group:
to search by group:
$ uni e group:hands
Name (Cldr)
👏 clapping hands ()
🙌 raising hands (celebration, gesture, hooray, raised)
🫶 heart hands (love)
👐 open hands ()
🤲 palms up together (prayer)
🤝 handshake (agreement, meeting)
🙏 folded hands (ask, high 5, high five, please, pray, thanks)
Group and search can be combined, and group:
can be abbreviated to g:
:
$ uni e g:cat-face grin
Name (Cldr)
😺 grinning cat (face, mouth, open, smile)
😸 grinning cat with smiling eyes (face, smile)
Like with search
, use -or
to OR the parameters together instead of AND:
$ uni e -or g:face-glasses g:face-hat
Name (Cldr)
🤠 cowboy hat face (cowgirl)
🥳 partying face (celebration, hat, horn)
🥸 disguised face (glasses, incognito, nose)
😎 smiling face with sunglasses (bright, cool)
🤓 nerd face (geek)
🧐 face with monocle (stuffy)
Apply skin tone modifiers with -tone
:
$ uni e -tone dark g:hands
Name (Cldr)
👏🏿 clapping hands: dark skin tone ()
🙌🏿 raising hands: dark skin tone (celebration, gesture, hooray, raised)
🫶🏿 heart hands: dark skin tone (love)
👐🏿 open hands: dark skin tone ()
🤲🏿 palms up together: dark skin tone (prayer)
🤝 handshake (agreement, meeting)
🙏🏿 folded hands: dark skin tone (ask, high 5, high five, please, pray, thanks)
The "heart hands" may not show as it's very recent. The handshake emoji supports setting individual skin tones per hand since Unicode 14, but this isn't supported, mostly because I can't really really think a good CLI interface for setting this without breaking compatibility (there are some other emojis too, like "holding hands" and "kissing" where you can set both the gender and skin tone of both sides individually). Maybe for uni v3 someday.
The default is to display only the gender-neutral "person", but this can be
changed with the -gender
option:
$ uni e -gender man g:person-gesture
Name (Cldr)
🙍♂️ man frowning (gesture, person frowning)
🙎♂️ man pouting (gesture, person pouting)
🙅♂️ man gesturing NO (forbidden, gesture, hand, person gesturing NO, prohibited)
🙆♂️ man gesturing OK (gesture, hand, person gesturing OK)
💁♂️ man tipping hand (help, information, person tipping hand, sassy)
🙋♂️ man raising hand (gesture, happy, person raising hand, raised)
🧏♂️ deaf man (accessibility, deaf person, ear, hear)
🙇♂️ man bowing (apology, gesture, person bowing, sorry)
🤦♂️ man facepalming (disbelief, exasperation, person facepalming)
🤷♂️ man shrugging (doubt, ignorance, indifference, person shrugging)
Both -tone
and -gender
accept multiple values. -gender women,man
will
display both the female and male variants, and -tone light,dark
will display
both a light and dark skin tone; use all
to display all skin tones or genders:
$ uni e -tone light,dark -gender f,m shrug
Name (Cldr)
🤷🏻♂️ man shrugging: light skin tone (doubt, ignorance, indifference, person shrugging)
🤷🏻♀️ woman shrugging: light skin tone (doubt, ignorance, indifference, person shrugging)
🤷🏿♂️ man shrugging: dark skin tone (doubt, ignorance, indifference, person shrugging)
🤷🏿♀️ woman shrugging: dark skin tone (doubt, ignorance, indifference, person shrugging)
Like print
and identify
, you can use -format
:
$ uni e g:cat-face -c -format '%(name): %(emoji)'
grinning cat: 😺
grinning cat with smiling eyes: 😸
cat with tears of joy: 😹
smiling cat with heart-eyes: 😻
cat with wry smile: 😼
kissing cat: 😽
weary cat: 🙀
crying cat: 😿
pouting cat: 😾
See uni help
for more details on the -format
flag.
With -as json
or -as j
you can output the data as JSON:
$ uni i -as json h€ý
[{
"cat": "Lowercase_Letter",
"char": "h",
"cpoint": "U 0068",
"dec": "104",
"html": "h",

"utf8": "68"
}, {
"cat": "Currency_Symbol",
"char": "€",
"cpoint": "U 20AC",
"dec": "8364",
"html": "€",
"name": "EURO SIGN",
"utf8": "e2 82 ac"
}, {
"cat": "Lowercase_Letter",
"char": "ý",
"cpoint": "U 00FD",
"dec": "253",
"html": "ý",
"name": "LATIN SMALL LETTER Y WITH ACUTE",
"utf8": "c3 bd"
}]
All the columns listed in -f
will be included; you can use -f all
to include
all columns:
$ uni i -as json -f all h€ý
[{
"bin": "1101000",
"block": "Basic Latin",
"cat": "Lowercase_Letter",
"char": "h",
"cpoint": "U 0068",

"script": "Latin",
"utf16be": "00 fd",
"utf16le": "fd 00",
"utf8": "c3 bd",
"width": "narrow",
"xml": "ý"
}]
This also works for the emoji
command:
$ uni e -as json -f all 'kissing cat'
[{
"cldr": "eye, face",
"cldr_full": "cat, eye, face, kiss, kissing cat",
"cpoint": "U 1F63D",
"emoji": "😽",
"group": "Smileys & Emotion",
"name": "kissing cat",
"subgroup": "cat-face"
}]
All values are always a string, even numerical values. This makes things a bit
easier/consistent as JSON doesn't support hex literals and such. Use jq
or
some other tool if you want to process the data further.
- Add "script" property (e.g.
uni i a -f '%(script)'
). Also supported in the list and print commands (uni list scripts
,uni p 'script:linear a'
.
- Fix build on Go 1.17 and earlier.
-
Add support for properties; they can be displayed with
%(props)
in-format
, and selected inprint
(e.g.uni print dash
). -
Add
uni list
command, to list categories, blocks, and properties. -
Allow explicitly selecting a block, category, or property in
print
withblock:name
(b:name
),category:name
(cat:name
,c:name
), orproperty:name
(prop:name
,p:name
).Also print an error if a string without prefix matched more than one group (i.e.
uni p dash
matches both the propertyDash
and categoryDash_Punctuation
). -
Add table layout with
-as table
. Also change-json
/-j
to-as json
or-as j
. The-json
flag is still accepted as an alias for compatibility. -
Change
-q
/-quiet
to-c
/-compact
;-as json
will print as minified if given, and-as table
will include less padding.-q
is still accepted as an alias for compatibility. -
Don't use the Go stdlib
unicode
package; since this is a Unicode 13 database and some operations would fail on codepoints added in Unicode 14 due to the mismatch.
-
Update import path to
zgo.at/uni/v2
. -
Add
oct
andbin
flags for-f
to print a codepoint as octal or binary. -
Add
f
format flag to change the fill character with alignment; e.g.%(bin r:auto f:0)
will print zeros on the left. -
Allow using just
o123
for an octal number (instead of0o123
). We can't do this for binary and decimal numbers (sinceb
andd
are valid hexidecimals), but no reason not to do it foro
.
-
Update to Unicode 14.0.
-
UTF-16 and JSON are printed as lower case, just like UTF-8 was. Upper-case is used only for codepoints (i.e. U 00AC).
-
uni print
can now print from UTF-8 byte sequence; for example to print the € sign:uni p utf8:e282ac uni p 'utf8:e2 82 ac' uni p 'utf8:0xe2 0x82 0xac'
Bytes can optionally be separated by any combination of
0x
,-
,_
, or spaces.
-
You can now use
uni p 0d40
to get U 28 by decimal.uni print 40
interprets the40
as hex instead of decimal, and there was no way to get a codepoint by decimal number. Since codepoints are much more more common than decimals, leaving off theU
andU
is a useful shortcut I'd like to keep. AFAIK there isn't really a standard(-ish) was to explicitly indicate a number is a decimal, so this is probably the closest.
-
Make proper use of the
/v2
import path so thatgo get
andgo install
work. (#26) -
Don't panic if
-f
doesn't contain any formatting characters.
-
Can now output as JSON with
-j
or-json
. -
-format all
is a special value to include all columns uni knows about. This is useful especially in combination with-json
. -
Add
%(block)
,%(plane)
,%(width)
,%(utf16be)
,%(utf16le)
, and%(json) to
-f`. -
Refactor the arp242.net/uni/unidata package to be more useful for other use cases. This isn't really relevant for
uni
users as such, but if you want to get information about codepoints or emojis then this package is a nice addition to the standard library'sunicode
package.
This changes some flags, semantics, and defaults in incompatible ways, hence
the bump to 2.0. If you use the dmenu-uni
script with dmenu or fzf, then
you'll need to update that to.
-
Remove the
-group
flag in favour ofgroup:name
syntax; this is more flexible and will allow adding more query syntax later.uni emoji -group groupname,othergroup Old syntax uni emoji -group groupname,othergroup smile Old syntax uni emoji -or group:groupname group:othergroup New syntax uni emoji -or group:groupname group:othergroup smile New syntax uni emoji -or g:groupname g:othergroup Can use shorter g: instead of group:
-
Default for
-gender
is nowperson
instead ofall
; including all genders by default isn't all that useful, and the gender-neutral "person" should be a fine default for most, just as the skin colour-neutral "yellow" is probably a fine default for most. -
Add new
-or
/-o
flag. The default forsearch
andemoji
is to show everything where all query parameters match ("AND"); with this flag it shows everything where at least one parameter matches ("OR"). -
Add new
-format
/-f
flag to control which columns to output and column width. You can now also print X11 keysyms and Vim digraphs. Seeuni help
for details. -
Include CLDR data for emojis, which is searched by default if you use
uni e <something>
. You can useuni e name:x
to search for the name specifically. -
Show a short terse help when using just
uni
, and a more detailed help onuni help
. I hate it when programs print 5 pages of text to my terminal when I didn't ask for it. -
Update Unicode data to 13.1.
-
Add option to output to
$PAGER
with-p
or-pager
. This isn't done automatically (I don't really like it when programs throw me in a pager), but you can define a shell alias (alias uni='uni -p'
) if you want it by default since flags can be both before or after the command.
- Fix tests of v1.1.0, requested by a packager. No changes other than this.
-
Update Unicode data from 12.1 to 13.0.
-
print
command supports codepoints as hex (0xff
), octal (0o42
), and binary (0b1001
). -
A few very small bugfixes.
- Initial release
Re-generate the Unicode data with go generate unidata
. Files are cached in
unidata/.cache
, so clear that if you want to update the files from remote.
This requires zsh and GNU awk (gawk).
-
https://github.com/philpennock/character
More or less similar to uni, but very different CLI, and has some additional features. Seems pretty good.
-
https://github.com/sindresorhus/emoj
Doesn't support emojis sequences (e.g. MAN SHRUGGING is PERSON SHRUGGING MAN, FIREFIGHTER is PERSON FIRE TRUCK, etc); quite slow for a CLI program (
emoj smiling
takes 1.8s on my system, sometimes a lot longer), search results are pretty bad (shrug
returns unamused face, thinking face, eyes, confused face, neutral face, tears of joy, and expressionless face ... but not the shrugging emoji), not a fan of npm (has 1862 dependencies). -
https://github.com/Fingel/tuimoji
Grouping could be better, doesn't support emojis sequences, only interactive TUI, feels kinda slow-ish especially when searching.
-
https://github.com/pemistahl/chr
Only deals with codepoints, not emojis.
-
gnome-characters
Uses Gnome interface/window decorations and won't work well with other WMs, doesn't deal with emoji sequences, I don't like the grouping/ordering it uses, requires two clicks to copy a character.
-
gucharmap
Doesn't display emojis, just unicode blocks.
-
KCharSelect
Many KDE-specific dependencies (106M). Didn't try it.
-
https://github.com/Mange/rofi-emoji and https://github.com/fdw/rofimoji
Both are pretty similar to the dmenu/rofi integration of uni with some minor differences, and both seem to work well with no major issues.
-
gtk3 emoji picker (Ctrl ; or Ctrl . in gtk 3.93 or newer)
Only works in GTK, doesn't work with
GTK_IM_MODULE=xim
(needed for compose key), for some reasons the emojis look ugly, doesn't display emojis sequences, doesn't have a tooltip or other text description about what the emoji actually is, the variation selector doesn't seem to work (never displays skin tone?), doesn't work in Firefox.This is so broken on my system that it seems that I'm missing something for this to work or something?
-
https://github.com/rugk/awesome-emoji-picker
Only works in Firefox; takes a tad too long to open; doesn't support skin tones.
Some alternatives people have suggested that I haven't looked at; make an issue or email me if you know of any others.
