@ -72,6 +72,14 @@ existing support and the extra stuff at
* iso-2022 charsets get unified on i/o.
With the change on 2003-01-06, decoding routines put `charset'
property to decoded text, and iso-2022 encoder pay attention
to it. Thus, for instance, reading and writing by
iso-2022-7bit preserve the original designation sequences.
The property name `preferred-charset' may be better?
We may have to utilize this property to decide a font.
* 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.)

2003-01-06 Kenichi Handa <handa@m17n.org>
* coding.c (CATEGORY_MASK_RAW_TEXT): New macro.
(detect_coding_utf_8, detect_coding_utf_16)
(detect_coding_emacs_mule, detect_coding_iso_2022)
(detect_coding_sjis, detect_coding_big5)
(detect_coding_ccl, detect_coding_charset): Change argument MASK
to DETECT_INFO. Update DETECT_INFO and return 1 if the byte
sequence is valid in this coding system. Callers changed.
(MAX_ANNOTATION_LENGTH): New macro.
(ADD_ANNOTATION_DATA): New macro.
(ADD_COMPOSITION_DATA): Argument changed. Callers changed. Call
ADD_ANNOTATION_DATA. The format of annotation data changed.
(ADD_CHARSET_DATA): New macro.
(emacs_mule_char): New argument ID. Callers changed.
(decode_coding_emacs_mule, decode_coding_iso_2022)
(decode_coding_sjis, decode_coding_big5, decode_coding_charset):
Produce charset annotation data in coding->charbuf.
(encode_coding_emacs_mule, encode_coding_iso_2022): Pay attention
to charset annotation data in coding->charbuf.
(setup_coding_system): Add CODING_ANNOTATE_CHARSET_MASK
coding->common_flags if the coding system is iso-2022 based and
uses designation.
(produce_composition): Adjusted for the new annotation data
format.
(produce_charset): New function.
(produce_annotation): Handle charset annotation.
(handle_composition_annotation, handle_charset_annotation): New
functions.
(consume_chars): Handle charset annotation. Utilize the above two
functions.
(encode_coding_object): If SRC_OBJECT and DST_OBJECT are the same
buffer, get the deleted text as a string and set
coding->src_object to that string.
(detect_coding, detect_coding_system): Use the new struct
coding_detection_info.
* coding.h (struct coding_detection_info): New structure.
(struct coding_system): Prototype of the member `detector'
adjusted.
(CODING_ANNOTATE_CHARSET_MASK): New macro.

* insdel.c (insert_from_gap): Fix argument to offset_intervals.
