Hi, I'm trying to report #10060, but a file in the report yielded by http://commons.wikimedia.org/w/index.php?title=Special%3APrefixindex&from=On+the+expression&namespace=6 truncates my bug report, no matter if it's given as URL or wikilink.
OK, I think I've got a first clue. In the file name, the letter after "from" (i.e. where the truncation occurs), which looks like an "a", is really a high Unicode character to be used in mathematical formulas. I remember now giving the corresponding file on Wikisource that name and copied it for the Commons upload. So it seems there is a problem with high Unicode characters. I'll try to upload the file under a different name.
Well, what do you know, I just reuploaded the file as [[:commons:Image:On the expression of a number.djvu]] and everything works perfectly. Therefore, I'm altering the summary and severity of this bug. Of course, the real culprit might be my browser (Mozilla Iceape 1.8.0.11, also tried Firefox/Iceweasel), but the characters are displayed properly on Commons and Wikisource.
Support for Unicode outside the BMP is often lacking. The characters in question look like black squares to me. This looks to be an upstream problem, anyway; you may want to report it at bugzilla.mozilla.org.
This is a limitation in MySQL's Unicode support -- non-BMP characters cannot be represented in Unicode columns (UCS-2 or UTF-8 with limitation to BMP). Removing block on bug 10060, since a change in behavior of Bugzilla will have no effect on a problem in MediaWiki's handling of DjVu images. Marking this bug as LATER, since there may not be a clear convenient workaround without jumping a lot of hoops. :P
+upstream: issue with how BZ handles urls with unicode characters. WONTFIXing this, its a upstream issue that we will never likely patch ourselves and there isn't really any point to having it sit around in LATER forever. Feel free to reopen when its fixed or if someone actually wants to work on it.
