* coding.c (decode_coding_iso2022): Pay attention to the byte
sequence of CTEXT extended segment, and retain those bytes as is.
2003-05-28 Kenichi Handa <handa@m17n.org>
* coding.c (ENCODE_UNSAFE_CHARACTER): Adjusted for the name change
of CODING_REPLACEMENT_CHARACTER.
(decode_coding_iso2022): If CODING_FLAG_ISO_SAFE, set
CODING_MODE_INHIBIT_UNENCODABLE_CHAR flag in coding->mode, and
check this flag on encoding.
(encode_coding_sjis_big5): Check
CODING_MODE_INHIBIT_UNENCODABLE_CHAR flag of coding->mode.
(Fset_terminal_coding_system_internal): Set
CODING_MODE_INHIBIT_UNENCODABLE_CHAR flag in terminal_coding.mode
instead of setting CODING_FLAG_ISO_SAFE flag in
terminal_coding.flags.
* coding.h (CODING_REPLACEMENT_CHARACTER): Renamed from
CODING_INHIBIT_CHARACTER_SUBSTITUTION.
(CODING_MODE_INHIBIT_UNENCODABLE_CHAR): New macro.
2003-05-28 Richard M. Stallman <rms@gnu.org>
* print.c (syms_of_print) <print-escape-nonascii>: Doc fix.
