I have a new Host that do not working probably . In other Hosts I had not
any problem . In this one , I could not write Farsi data ( Unicode ) in Bank
by web form . According to my ASP source , maybe this server thinks these are
nul characters . Maybe this Host Can not support Farsi or Unicode :

Microsoft JET Database Engine error '80040e21'
Index or primary key cannot contain a Null value.

There is not this problem for English data . I'm looking for your Assist :
