Thanks @ethanresnick for your answer, your rewording helps me.
The range “U+0000 to U+007F” confused me because it overlaps with other ranges of allowed, unallowed and not recommended characters. It isn’t clear to know exactly what is allowed or not without to take the “Reserved Characters” one by one.
I think something like that would be more verbose but more obvious (changes in bold characters) :
The following “globally allowed characters” MAY be used anywhere in a member name:
- U+0061 to U+007A, “a-z”
- U+0041 to U+005A, “A-Z”
- U+0030 to U+0039, “0-9”
- U+0080 and above (not recommended, not URL safe)
Additionally, the following characters are allowed in member names, except as the
first or last character:
- U+002D HYPHEN-MINUS, “-”
- U+005F LOW LINE, “_”
- U+0020 SPACE, " " (not recommended, not URL safe)
The following characters MUST NOT be used in member names:
- U+0000 to U+001F, Control Characters
- U+007F DELETE
[the same here…]
If I’m not doing mistake, all the characters of the U+0000 to U+007F are explicitly specified in this version.
What do you think of this proposal ?
