10 years ago additional comment:
this problem also connected to another problem of showing empty channels when clicking on tabs (jquery update), but working normally when refreshing the page. It seems that this happens when user having non-english nickname leaves last comment (with "?" in circle instead of first letter of the name). Fixing this problem automatically fixes this strange behaviour of jquery.
Tristan should be aware of it - this was reported by @hajduk.
The solution
core/lib/functions.render.php:182
change
return "".(!empty($member["username"]) ? strtoupper($member["username"][0]) : " ")."";
to
return "".(!empty($member["username"]) ? mb_strtoupper(mb_substr($member["username"], 0, 1, "UTF-8"), "UTF-8") : " ")."";
Will try to make poll request (correct?) later on. Shame but never used Github for such things.
