const Standard_Integer  maxsize 
)
static

Converts Unicode ExtendedString <fromstr> to non-ASCII CString <tostr> in GB format, limited to <maxsize> characters. To translate the whole <fromstr>, use more than twice the length of <fromstr>. Returns true if <maxsize> has not been reached before end of conversion.
