[mediawiki/extensions/Echo@master] Fix DiscussionParser failing in certain languages
Comment Actions
I wrote a little script that iterates all known languages, and found this failure happens when the user's interface language is set to one of these: bo, ckb, dz, km, ks, ks-arab, ku-arab, skr. The reason is a regular expression in the DiscussionParser that is not set to Unicode mode via /u. It doesn't look like this is necessary, because there are no non-ASCII characters in this pattern. But what happens is that the initial \h in this pattern matches an 8-bit part of a Unicode character that happens to be in the right position in one of these languages. In /u mode the \h sequence only matches full Unicode characters.
