Unicode and Scheme
I mentioned earlier that I've submitted a draft SRFI about changes and
extensions to R5RS to make Scheme extended-character-set-friendly
(Unicode-friendly in particular).
I've drafted two additional proposals for:
~ Specifications for what happens if Unicode codepoints are,
indeed representable as CHAR? values.
~ Specifications for identifier syntax and meaning if identifiers
can be written using non-ASCII, Unicode characters.
These can be found at:
* "Permitting and Supporting Extended Character Sets":
basic changes needed to R5RS to make Unicode-based Schemes
practical and conformant.
* "Scheme Characters as (Extended) Unicode Codepoints":
Defining the CHAR? type to be a superset of Unicode codepoints.
* "Unicode Identifiers":
Internationalizing the Scheme Programming Language.
Note: "Unicode Identifiers" is the roughest of the three documents
and I'm certain I could use some help with it.
It also contains some other string-related documents which aren't
Unicode-specific but which do make proposals that would interact with
both Unicode characters and strings and FFIs.
