What's more important than your lack of knowledge is that the case
conversion outside the ASCII range depends on the encoding. I.e.,
with UTF-8 you get one case conversion, with Latin-1 a different one,
with Latin-2 yet another one, with KOI8-R yet another one etc. So if
we used case conversion for non-ASCII characters, we would have to
ensure that the Forth system knows the encoding of the program. Also,
case conversion in general is much more complicated than for ASCII,
and language-dependent. E.g., in Turkish the conversions for i and I
are different than in most other languages.
Gforth's solution to that (and one that I recommend for all systems)
is to be case-insensitive only for the ASCII characters. The
motivation for case insensitivity is that the standard words are in
upper case, while most programmers nowadays prefer to write and read
most of them in lower case, and that's covered by that solution. For
programmer-defined words, who needs case-insensitivity?
