I have, but it's something else to deal with, that being honest, if I
don't have to deal with it, I won't. (And I don't mind re-inventing the
wheel). Creating B0 for me is as much about learning how to make a
compiler (from scratch), as it is about creating a new language.

At the moment, it only supports ASCII source, however there are heavy
consideration for UTF-16 source to be implemented shortly.
For reasons why UTF-16, look through the thread called "Unicode"
started by me in this NG, not that long ago.
The one thing that may hamper that ambition, is the lack of support in
regards to C and its supporting libraries (B0 for the moment is
implemented in C). On Windows, it's fine (MS VC++ provides everything I
need), but it's *nix that I am concerned about (gcc + glibc).
It's something that I have to look at more. However as a bare minimum,
I will allow comments and strings to be UTF-8, while identifiers/labels
and operators are restricted to ASCII (eg _,0..9,a..z,A..Z).
