Unicode problem in customer fields

[atfmova]

Hi everyone,

I have installed OTRS5 and I've integrated it with our CRM application through customer database using DBI:ODBC to connect to our Oracle database.
So I can see our CRM customers in "Customer administration" part.

the problem is that the unicode fields like name, or family name or .... which are in Farsi, are shown with question marks like ?????? ??? ????

To solve:
1) I have added NLS_LANG=AMERICAN_AMERICA.UTF8 environment variables to bashrc. I have tested my ODBC driver using a perl script and result is OK. it shows the result in Farsi.
2) I have added SourceCharset->'utf-8' and DestCharset->'utf-8' to Kernel/Config.pm
3) I have added $ENV{NLS_LANG} = 'AMERICAN_AMERICA.UTF8' to Kernel/Config.pm

But OTRS still shows the names like ????
Please help me on this.
