In my System, It is seeing as ਸ ਧਾ ਰ ਨ

FireShot Capture 36 - File_Types of Sentences-pa.svg - Wikim_ - https___commons.wikimedia.org_wiki.png (194×280 px, 14 KB)

I found that there is no problem in full size rendering.

Same is happening in https://commons.wikimedia.org/wiki/File:Sentence_Structure-pa.svg

This seems to be about the thumbnails in PNG format and not about the original file in SVG format itself. For future reference, please follow https://www.mediawiki.org/wiki/How_to_report_a_bug - thanks!

Aklapper added a parent task: T43371: Thumbnail/imagescaler (tracking).

@satdeep_gill: Please only set a task assignee if the assignee has explicitly agreed before. (Not sure in this case; maybe the field was unintentionally reset.) Thanks!

The same is happening to any text rendering of librsvg, because librsvg is going more worse and more worse instead of better: T36947. So I do mean this report is a dupe.

because librsvg is going more worse and more worse instead of better

@Perhelion: If you find specific issues, please file bug reports. While frustration is sometimes understandable, generalized statements don't help anyone.

We should test this when we upgrade librsvg

imho a duplicate of T36947, which is not a subtask of Updating librsvg, but maybe a subtask of reevaluating svg-render T40010

"Incorrect text spacing when transform is not 1:1" will be fixed in librsvg 2.51.2 (and librsvg 2.50.6, once backported) according to https://gitlab.gnome.org/GNOME/librsvg/-/issues/730 (thanks to JoKalliauer for investigation and upstreaming).
