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.
