Frank and Daniel,

Problem solved using string conversion function from 8 bit JIS7 to 
UNICODE. I use the methods provided by the Qt library (by Trolltech) but 
Daniel suggestion is another possibility. I tried to discover the text 
codec automatically without success so at the end I'm asking the user 
the text code to be use.

I believe that is a good idea to move GDAL to UNICODE if possible, 
getting rid of char* and using unsigned short * or, even better, a C++ 
string class that supports UNICODE. But this will not be a easy task as 
I have discover when trying to add support in my application for UNICODE.
