Unicode section needs to be updated
Several issues I just noticed:
- [x] [open](https://cmucl.common-lisp.dev/docs/cmu-user/html/Files.html) doesn't even list the `:external-format` keyword and other keywords mentioned in the description.
- [x] [Methods for
strings](https://cmucl.common-lisp.dev/docs/cmu-user/html/Methods-for-Strings.html)
needs updating because some of these functions are actually in the
`unicode` package.
- [x] Update `string-downcase` and friends
- [ ] Update `string=` and friends
- [ ] Update `string-equal` and friends
- [ ] Update `string-trim` and friends
- [x] Add some missing documentation
- [x] `WITH-STRING-CODEPOINT-ITERATOR`
- [x] `WITH-STRING-GLYPH-ITERATOR`
- [x] New loop keywords `being the codepoint` and `being the glyph`
- [x] Reader supports `#\u+nnnn` where `nnnn` is larger than 16 bits. While not really quite legal, it is immensely useful.
