Oh, I *can* use UTF-8 in identifiers?? nooo:
Identifiers name program entities such as variables and types. An
identifier is a sequence of one or more letters and digits. The first
character in an identifier must be a letter.
identifier = letter { letter | unicode_digit } .
...
Letters and digits
The underscore character _ (U+005F) is considered a letter.
letter = unicode_letter | "_" .
decimal_digit = "0" … "9" .
octal_digit = "0" … "7" .
hex_digit = "0" … "9" | "A" … "F" | "a" … "f" .
but `unicode_letter` - what is that? Does that include such as æ ? If so
then I guess it would also allow ⻄ too.
I have seen source code from chinese authors that has comments in cn
traditional. So does this mean, in theory, I can use any valid unicode
letter from alphabet (or even pictograpic) language scripts??
