If you go to the list of parser extension tags on the Hebrew Wikipedia, you'll see one tag whose name appears in jumbled mojibake instead of Unicode. This is probably the localized Hebrew version of <section> from LabeledSectionTransclusion.
I cannot reproduce it on my local wiki.
Version: 1.24rc
Severity: normal

Hmm. weird, I didn't think we localized parser tags.
Anyways, caused by using the htmlentities escaping function (Why would we use that function instead of htmlspecialchars, I don't know), which prior to php 5.4 used iso 8859-1 as its default encoding. Presumably you are using 5.4 which uses utf-8 as its encoding.
