What is the value of ispell-program-name?  After you invoke
ispell-buffer for the first time in an Emacs session, type

  M-: ispell-program-name RET

and tell what it displays.  If it says your spell-checking program is
Ispell, then the above error message is expected: Ispell does not
support languages whose text cannot be encoded in single-byte
encoding, while the text you show needs something like UTF-8 to
encode.

Also, type this:

  M-: ispell-current-dictionary RET

and tell what it displays.

Thanks.
