Yes and to confirm it, I just did it again:

samba-tool user create User2 passw2rd* --given-name=Jane --surname=Doe
User 'User2' created successfully

samba-tool user delete User2
Deleted user User2

samba-tool user create User2 passw2rd* --given-name=Jane --surname=Doe
User 'User2' created successfully

samba-tool group addmembers wingroup User2
Added members to group wingroup

I cannot confirm your problem, I can create a user and add it to a
group, I even tried it with the username that doesn't work for you and
it worked for me. I am beginning to think it might be easier to get
your user to change their name ;-)

I think it may be a locale problem, what locale are you using ?
