There's an entry in my logfiles for a bot trying to access a specific URL which causes a server error:
'ascii' codec can't encode character u'\ufeff' in position 14: ordinal not in range(128)

Error - <type 'exceptions.UnicodeEncodeError'>: 'ascii' codec can't encode character u'\ufeff' in position 14: ordinal not in range(128)

ayleph, thanks for submitting. Can you submit steps to reproduce?

Sorry for the delay; I don't remember getting an email with your comment. Here's a recent bug report on IRC.

Besnik_b_ | I think I found a bug: if you put a "ë" character in the identifier of a collection, Mediagoblin will save the change, but you cannot access the URL any more. The faulty character is accepted without any complain or notification.
Besnik_b_ | Here you are the link to see that in action:
Besnik_b_ | The identifier in question, "firefox-os-ne-shqip-versioni-tablet" was changed to "firefox-os-në-shqip-versioni-tablet", which render as "firefox-os-n%AB-shqip-versioni-tablet" in the browser

This isn't a problem with MediaGoblin code. It's an issue of an incorrect locale being used by Werkzeug. Recent Werkzeug (> 0.11) includes a work-around for this and assumes UTF-8 locale if the system locale reports ASCII. Closing ticket as 'invalid' since this has nothing to do with MediaGoblin code.
