Problems, fixmes and other issues in the emacs-unicode branch
|
||
|
||
Notes by fx to record a few things. handa needs to check them --
|
||
don't take too seriously, especially with regard to completeness.
|
||
|
||
Do take seriously that you don't want this CVS branch unless you're
|
||
actually working on it. If you just want to edit Unicode and/or unify
|
||
iso-8859 et al, see the existing support and the extra stuff at
|
||
<URL:ftp://dlpx1.dl.ac.uk/fx/emacs/Mule>. Editing support is mostly
|
||
orthogonal to the internal representation.
|
||
|
||
* SINGLE_BYTE_CHAR_P returns true for Latin-1 characters.
|
||
|
||
* Grok UTF-8 surrogates.
|
||
|
||
* Rationalize character syntax and its relationship to the Unicode
|
||
database. Specifically, the latin-N.el files aren't consistent for
|
||
common characters.
|
||
|
||
* Fontset handling and customization needs work.
|
||
|
||
* Likewise for charset and coding system priorities.
|
||
|
||
* The relevant bits of latin1-disp.el need porting (and probably
|
||
re-naming/updating). See also cyril-util.el.
|
||
|
||
* Quail files need work now the encoding is irrelevant. E.g. make
|
||
unified Latin pre- and post- methods.
|
||
|
||
* What to do with the old coding categories stuff?
|
||
|
||
* Syntax for symbols &c in characters needs looking at.
|
||
|
||
* The preferred-coding-system property of charsets should probably be
|
||
junked unless it can be made more useful now.
|
||
|
||
* find-coding-systems-for-charsets needs re-writing.
|
||
|
||
* find-multibyte-characters needs looking at.
|
||
|
||
* Implement Korean cp949/UHC and any other important missing
|
||
charsets.
|
||
|
||
* Check up on tcvn and alternativnj.
|
||
|
||
* Lazy-load tables for unify-charset somehow?
|
||
|
||
* Should translation tables for {en,de}code and input work now or be
|
||
scrapped?
|
||
|
||
* Defining CCL coding systems currently doesn't work.
|
||
|
||
* iso-2022 charsets get unified on i/o.
|
||
|
||
* Revisit locale processing: look at treating the language and
|
||
charset parts separately. (Language should affect things like
|
||
speling and calendar, but that's not a Unicode issue.)
|
||
|
||
* Handle Unicode combining characters usefully, e.g. diacritics, and
|
||
handle more scripts specifically (<28> la Devanagari). There are
|
||
issues with canonicalization.
|
||
|
||
* Bidi is a separate issue.
|
||
|
||
* DTRT with X keysyms. We should get the right unicode for a given
|
||
keysym, not decode raw bytes in some ill-defined coding system.
|
||
(fx has some data on keysyms v. unicodes.)
|
||
|
||
* We need tabular input methods, e.g. for maths symbols. (Not
|
||
specific to Unicode.)
|
||
|
||
* Need multibyte text in menus, e.g. for the above. (Not specific to
|
||
Unicode.)
