Dear SPIP team,
today, I used SPIP for the first time. As a diligent user, one of the first things I did was to change my password. I noted that if my password contains an umlaut (e.g. ü, u with trema), the password is not changed and a blank page is displayed instead. I would expect instead that my password is changed, and some confirmation displayed. Non-ASCII characters in passwords should provide no problem, especially for an application that makes internationalization a priority.
A second issue is that I haven't find a way to post a proper bug report on your website; hence the message to the mailing list.
Best,
Jonas
