Subject: "international" characters?
Greetings! The phrase "international characters" is used under small group (2.1.1) for named expression identifiers. It is noted that some applications may not display a glyph but an ISO 10646 code. But, under text (string) (4.1), it is noted that "implementations *should* support Unicode strings, but *shall* at least support strings of ASCII characters." Question: In all cases are we talking about Unicode strings in one of the defined representations (UTF-8), etc.? Question: Or, is the string (4.1) language meant to allow a non-Unicode based encoding? Question: If a non-Unicode based encoding, which definition of that encoding are we using? I don't necessarily disagree but it does seem odd that Unicode support is required for identifiers but optional under text. Noting that Unicode "support" doesn't necessarily mean that you get a meaningful display of the text. (Can someone more familiar with display issues comment on the usual behavior for missing characters? I seem to recall that all you usually see are some glyph but I don't remember which one. I don't recall it being the Unicode code number.) Hope everyone is having a great day!
