This is one of the HP-UX encodings. As far as I can see, there is no IANA name for it but I would suggest: HP-TURKISH8 TURKISH8 As it is know as "turkish8" on HP-UX itself. Mapping file attached.

Where did you get this information? Without reference I have no reason to trust the information.
Same comment as #5464
I verified the data myself. The trunk has the new module.
