Programs with non-ascii identifiers do not
link, under Mac OS X 10.3 using GDC 0.10...


They use the mangled name as a label for
the assembler, and then choke on the UTF-8:

unialpha.d:

Gives the error:

Here's the disasm:

Similar errors for variables:

Not sure how this can be fixed, without
changing the way that D mangles the names...

Both programs compile just fine on Linux.

If you are feeling like testing or something,
here are the rest of the Universal Alphas :

I think Walter officially acknowledged the phrase
"unicode alpha" as just a typo for universal...
(the meaning is that it can't start with a digit)

I've been only testing the name mangling, thus it shouldn't be important what scripts I check.

This shoulde be clarified. I suppose that "digits" are only "0123456789" - there are loads of other digits in Unicode.

Why is an ancient (1999) version used in the documentation? I've tried codepoints that are assigned in the current standard bu
weren't in the 1999 one, and as you might have guessed even currently reserved codepoints weren't caught by the frontent...

Yes, the quoted C99 standard (which isn't all that "ancient") used:
> Digits: 0660-0669, 06F0-06F9, 0966-096F, 09E6-09EF, 0A66-0A6F,

> 0E50-0E59, 0ED0-0ED9, 0F20-0F33

But I'm also thinking that a "digit" here meant [0-9]...
I think a "letter" to Walter is just [a-zA-Z], as well ?

And I agree, it would be a lot easier to just say that.
