I do not know if the following link could also help :


The more I read, the more I feel lost about encodings in Console/.Net...
When I compile Jacob's code (I used Gnome terminal), I have this :

IL_0000:  ldstr bytearray (
        48 00 65 00 6c 00 6c 00 6f 00 20 00 57 00 6f 00  
        72 00 6c 00 64 00 21 00 20 00 f3 97 50 4e 00

Wasn't the string supposed to be encoded as UTF-16 (or at is, is it
encoded in UTF-16 when the assembly is loaded in memory) ? I see only
one nul byte at the end...

If the string is wrote back on a terminal, I suppose (by having a quick
look at the mono source code) it is transposed in UTF-8 next written in
stdout ? Another part of my question is about console fonts
management/unicode in a tty, documentation around is very scattered and
fuzzy I can't figure out how things works precisely... (I was talked
about ACM, SFM, 4 internals mappings handled by the kernel, 256/512
chars fonts...). Can someone help me in putting the right brick of
knowledge at the right place ?

Kind regards,
