Then let's forget about char, and communicate via email. Shouldn't be
a problem there.

Yes. We need to solve the following problems:

- Memory representation of the characters that come over the wire. As
I mentioned before I like the mlterm way and am thinking to borrow
from there.

- Understand the Windows Text and Font APIs. To be more specific,
given a character code, UTF-8 or unicode, and a font, we need to
locate the corresponding glyph from the font, and ask windows to draw
that glyph. Microsoft's MSDN is your best friend here.

- Implement shaping and BIDI, again borrowing from current
implementations.


I suggest that you take the second one, and I will take the
first. What do you think ?

I don't see any need to change the "back-end" that is the low level
communication and encryption logic. We are lucky that encryption
algorithms used in ssh are not language depdnedent ;)
