OK, this is second step. First step is that if I want to use GrText(...,
MWTF_ASCII) Latin1 encoding is not loaded. May I do direct T1lib calls
from the client?

The problem is T1lib does not accept unicode indices. It accepts 0-255
index and uses currently loaded encoding to display it. So to do it
correctly Microwindows would need to have a map of "unicode-index : font
and encoding to use in T1" and reconfigure T1 dynamically. Or just load
fonts with different encoding as different fonts.

P.S. I have seen GdConvertEncoding
I would not call
*ostr8++ = (unsigned char)ch;
a "UNICODE suport".
