UTF-8/unicode bug in username/JID

LG1 · February 12, 2006, 4:01pm

Hi,

I did create a user “b\u20acn” using Spark but I can not login. Using the adminconsole to edit this users causes an exception. A short application using Smack can login, so it seems to be a Spark problem.

\u20ac is the “Euro Sign”, so the user is called “bEn” while the E is not an E but the Euro Sign.

Am I allowed to use this character in a name?

Has someone similar problems with special characters?

You can check the list of supported characters from the XMPP-node here http://www.xmpp.org/specs/rfc3920.html#nodeprep

Hi Alex,

as far as I understand the specifications every unicode 3.2 character is allowed for the username (XMPP node identifier) except "&’’/:<>@[/b].

The Euro Sign is a UCS-2 or unicode 1.0 character and thus allowed.

Do you agree?

What exception are you receiving in the admin console?

Hi Alex,

I know a nice game, it’‘s called keep the (in this case non-paying) customer busy. We should play it together, shouldn’'t we?

My question was a complete different one, I’'m not interested in the admin console or the exception. The admin console uses UTF-8 encoding for the URL (/user-properties.jsp?username=b%E2%82%ACn) for “bEn” while the value is stored as unicode in the database ( http://www.jivesoftware.org/community/thread.jspa?threadID=18000 ).

u20ac is the unicode representation for the ? “Euro Sign”. I wonder why unicode instead of UTF-8 (“0xE2 0x82 0xAC”) is used to store the user name (Unicode/UTF-8 reference: http://de.wikipedia.org/wiki/UTF-8#Beispiele ).

I’'m not happy to post the exception here as this is the Spark forum.
