yes, sorry, i wasn't precise when i said "any utf-8".

yes.

at this point, if a user tries to use one of the characters illegal in
jcr names, he'll get an error (not a validation error, a server
error). so you won't get into a state where he creates an account but
then can't use it.

foxmarks will need to incorporate this fix in order to allow existing
users with this problem to access their data and to allow new users to
include the characters at issue.

you're right, of course, but reality isn't always that easy or simple
:) i'll probably spend the time to refactor the next time we require a
migration.
