I discovered this problem in Debian Edu/Squeeze. When a user with a
non-ASCII character in the third position of the first or last name is
created, the generated username contain a non-valid UTF-8 character.
In Debian Edu, our gosa.conf contain the following rule:
idGenerator="{%givenName[3-6]}{%sn[3-6]}".
When using UTF-8, the range [3-6] at the moment do not refer to
characters, but bytes in the UTF-8 string. This caused the user 'Gunnar
Grændal' to get a propsed username with gungr?, where ? was half the
UTF-8 bytestream for æ. I believe it would be better if [3-6] refered
to characters 3-6, not bytes 3-6.
As non-ASCII usernames can cause problem when trying to log in to
different systems, I believe it would be best if usernames are always
converted to ASCII, preferably using the //TRANSLIT rule in glibc.
For the example above, one would then end up with "echo gungræ | iconv
-t ASCII//TRANSLIT" = gungrae as the proposed username.
