First part of interactive checks that coding systems encode regions.
2008-01-21 Aidan Kehoe <kehoea@parhasard.net>
* coding.el (decode-coding-string):
(encode-coding-string): Accept GNU's NOCOPY argument for
these. Todo; write compiler macros to use it.
(query-coding-warning-face): New face, to show unencodable
characters.
(default-query-coding-region-safe-charset-skip-chars-map):
New variable, a cache used by #'default-query-coding-region.
(default-query-coding-region): Default implementation of
#'query-coding-region, using the safe-charsets and safe-chars
coding systemproperties.
(query-coding-region): New function; can a given coding system
encode a given region?
(query-coding-string): New function; can a given coding system
encode a given string?
(unencodable-char-position): Function API taken from GNU; return
the first unencodable position given a string and coding system.
(encode-coding-char): Function API taken from GNU; return CHAR
encoded using CODING-SYSTEM, or nil if CODING-SYSTEM would trash
CHAR.
((unless (featurep 'mule)): Override the default
query-coding-region implementation on non-Mule.
* mule/mule-coding.el (make-8-bit-generate-helper): Eliminate a
duplicate comment.
(make-8-bit-choose-category): Simplify implementation.
(8-bit-fixed-query-coding-region): Implementation of
#'query-coding-region for coding systems created with
#'make-8-bit-coding-system.
(make-8-bit-coding-system): Initialise the #'query-coding-region
implementation for these character sets.
(make-8-bit-coding-system): Ditto for the compiler macro version
of this function.
* unicode.el (unicode-query-coding-skip-chars-arg): New variable,
used by unicode-query-coding-region, initialised in
mule/general-late.el.
(unicode-query-coding-region): New function, the
#'query-coding-region implementation for Unicode coding systems.
Initialise the query-coding-function property for the Unicode
coding systems to #'unicode-query-coding-region.
* mule/mule-charset.el (charset-skip-chars-string): New
function. Return a #'skip-chars-forward argument that skips all
characters in CHARSET.
(map-charset-chars): Function synced from GNU, modified to work
with XEmacs. Map FUNC across the int value charset ranges of
CHARSET.
