It seems it's not documented but looking at the logic in charge of validating the First Name, Middle and Last Names they are indeed subject to character validation. Those are slightly different from the username validation. The restriction is:
It can start with (one or more) space(s), any letter, ', -, _,

We have LDAP synch process and one of the users is having special characters in his last name in Active Directory. This user synchronization fails due to the special characters.
I tried creating a new user in Appian designer and entered special characters in last name, but it doesn't allow entering many of the special characters except few (like @ _- etc)

I have attached the screen shot for the same.
Same behaviour is seen with first name also.

The only restricted fields are:

1. Username
2. Email (since it has to contain the @)

These restrictions cannot be changed.
