hi
in sometimes when i want to save non english(in this case i use persian) character in the CB profile from the back-end , the character change to ???? and save in database.
look at the picture:

this problem only occur for additional field that i added that.(and it's label is persian too)
are you need additional information?
this problem some time occur not at all time, sime time when i edit some data of that's field.i was can't find logical for this problem time's.

hi again kerileon and excuse me for up the old topic but in 4 month ago i set the collection such as you can see in the attached picture
in the 1 , 2 , 3 not have any problem but in the 4, 5 i have ???? problem.
The common point of all the problem fields is that they are dumped through back-end management.
some times(only some time) when i edit some user through back-end, this problem is occur...
how can i solve that?
