Validation fails when there are accent in the required variable

[GoogleCodeExporter]

Hi,

When a required variable (like 'namePerson/first' for example) contains a word 
with an accent (like the in the following letters: 
à,â,ä,é,é,ê,ë,î,ï,ô,ö,û,ü), the authentification fails (and it 
works with all the required variable that do not contain an accent).

Thanks in advance to try to fix that bug.
