Support new IGNORE-INVALID-SEQUENCESP argument, #'query-coding-region. lisp/ChangeLog addition: 2009-02-07 Aidan Kehoe <kehoea@parhasard.net> * coding.el (query-coding-clear-highlights): Rename the BUFFER argument to BUFFER-OR-STRING, describe it as possibly being a string in its documentation. (default-query-coding-region): Add a new IGNORE-INVALID-SEQUENCESP argument, document that this function does not support it. Bind case-fold-search to nil, we don't want this to influence what the function thinks is encodable or not. (query-coding-region): Add a new IGNORE-INVALID-SEQUENCESP argument, document what it does; reflect this new argument in the associated compiler macro. (query-coding-string): Add a new IGNORE-INVALID-SEQUENCESP argument, document what it does. Support the HIGHLIGHT argument correctly. * unicode.el (unicode-query-coding-region): Add a new IGNORE-INVALID-SEQUENCESP argument, document what it does, implement this. Document a potential problem. Use #'query-coding-clear-highlights instead of reimplementing it ourselves. Remove some debugging messages. * mule/arabic.el (iso-8859-6): * mule/cyrillic.el (iso-8859-5): * mule/greek.el (iso-8859-7): * mule/hebrew.el (iso-8859-8): * mule/latin.el (iso-8859-2): * mule/latin.el (iso-8859-3): * mule/latin.el (iso-8859-4): * mule/latin.el (iso-8859-14): * mule/latin.el (iso-8859-15): * mule/latin.el (iso-8859-16): * mule/latin.el (iso-8859-9): * mule/latin.el (windows-1252): * mule/mule-coding.el (iso-8859-1): Avoid the assumption that characters not given an explicit mapping in these coding systems map to the ISO 8859-1 characters corresponding to the octets on disk; this makes it much more reasonable to implement the IGNORE-INVALID-SEQUENCESP argument to query-coding-region. * mule/mule-cmds.el (set-language-info): Correct the docstring. * mule/mule-cmds.el (finish-set-language-environment): Treat invalid Unicode sequences produced from invalid-sequence-coding-system and corresponding to control characters the same as control characters in redisplay. * mule/mule-cmds.el: Document that encode-coding-char is available in coding.el * mule/mule-coding.el (make-8-bit-generate-helper): Change to return the both the encode-program generated and the relevant non-ASCII charset; update the docstring to reflect this. * mule/mule-coding.el (make-8-bit-generate-encode-program-and-skip-chars-strings): Rename this function; have it return skip-chars-strings as well as the encode program. Have these skip-chars-strings use ranges for charsets, where possible. * mule/mule-coding.el (make-8-bit-create-decode-encode-tables): Revise this to allow people to specify explicitly characters that should be undefined (= corresponding to keys in unicode-error-default-translation-table), and treating unspecified octets above #x7f as undefined by default. * mule/mule-coding.el (8-bit-fixed-query-coding-region): Add a new IGNORE-INVALID-SEQUENCESP argument, implement support for it using the 8-bit-fixed-invalid-sequences-skip-chars coding system property; remove some debugging messages. * mule/mule-coding.el (make-8-bit-coding-system): This function is dumped, autoloading it makes no sense. Document what happens when characters above #x7f are not specified, implement this. * mule/vietnamese.el: Correct spelling. tests/ChangeLog addition: 2009-02-07 Aidan Kehoe <kehoea@parhasard.net> * automated/query-coding-tests.el: Add FAILING-CASE arguments to the Assert calls, making #'q-c-debug mostly unnecessary. Remove #'q-c-debug. Add new tests that use the IGNORE-INVALID-SEQUENCESP argument to #'query-coding-region; rework the existing ones to respect it.

;;; Commentary:

;; For Vietnamese, the character sets VISCII and VSCII are supported.

;;; Code:

;; Vietnamese VISCII.  VISCII is 1-byte character set which contains
;; more than 96 characters.  Since Emacs can't handle it as one
;; character set, it is divided into two: lower case letters and upper
;; case letters.
