+
+       The following changes (and some of 2002-08-20 changes of mine) are
+       for handling syntax, category, and case conversion for unibyte
+       characters by converting them to multibyte on the fly.  With these
+       changes, we don't have to setup syntax and case tables for unibyte
+       characters in each language environment.
+
+       * abbrev.c (Fexpand_abbrev): Convert a unibyte character to
+       multibyte if necessary.
+
+       * bytecode.c (Fbyte_code): Likewise.
+
+       * character.h (LEADING_CODE_LATIN_1_MIN) 
+       (LEADING_CODE_LATIN_1_MAX): New macros.
+       (unibyte_to_multibyte_table): Extern it.
+       (unibyte_char_to_multibyte): New macro.
+       (MAKE_CHAR_MULTIBYTE): Use unibyte_to_multibyte_table.
+       (CHAR_LEADING_CODE): New macro.
+       (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE): New macro.
+
+       * character.c (unibyte_to_multibyte_table): New variable.
+       (unibyte_char_to_multibyte): Move to character.h and defined as
+       macro.
+       (multibyte_char_to_unibyte): If C is an eight-bit character,
+       convert it to the corresponding byte value.
+
+       * charset.c (Fset_unibyte_charset): If the dimension of CHARSET is
+       not 1, singals an error.  Update the elements of
+       unibyte_to_multibyte_table.
+       (init_charset_once): Initialize unibyte_to_multibyte_table.
+       (syms_of_charset): Define the charset `iso-8859-1'.
+
+       * casefiddle.c (casify_object): Fix previous change.
+
+       * cmds.c (internal_self_insert): In a multibyte buffer, insert C
+       as is without converting it to unibyte.  In a unibyte buffer,
+       convert C to multibyte before checking the syntax.
+
+       * lisp.h (unibyte_char_to_multibyte): Extern deleted.
+
+       * minibuf.c (Fminibuffer_complete_word): Use the macro
+       FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE.
+
+       * regex.h (struct re_pattern_buffer): New member target_multibyte.
+
+       * regex.c (RE_TARGET_MULTIBYTE_P): New macro.
+       (GET_CHAR_BEFORE_2): Check target_multibyte, not multibyte.  If
+       that is zero, convert an eight-bit char to multibyte.
+       (MAKE_CHAR_MULTIBYTE, CHAR_LEADING_CODE): New dummy new macros for
+       non-emacs case.
+       (PATFETCH): Convert an eight-bit char to multibyte.
+       (HANDLE_UNIBYTE_RANGE): New macro.
+       (regex_compile): Setup the compiled pattern for multibyte chars
+       even if the given regex string is unibyte.  Use PATFETCH_RAW
+       instead of PATFETCH in many places.  To handle `charset'
+       specification of unibyte, call HANDLE_UNIBYTE_RANGE.   Use bitmap
+       only for ASCII chars.
+       (analyse_first) <exactn>: Simplified because the compiled pattern
+       is multibyte.
+       <charset_not>: Setup fastmap from bitmap only for ASCII chars.
+       <charset>: Use CHAR_LEADING_CODE to get leading codes.
+       <categoryspec>: If multibyte, setup fastmap only for ASCII chars
+       here.
+       (re_compile_fastmap) [emacs]: Call analyse_first with the arg
+       multibyte always 1.
+       (re_search_2) In emacs, set the locale variable multibyte to 1,
+       otherwise to 0.  New local variable target_multibyte.  Check it
+       to decide the multibyteness of STR1 and STR2.  If
+       target_multibyte is zero, convert unibyte chars to multibyte
+       before translating and checking fastmap.
+       (TARGET_CHAR_AND_LENGTH): New macro.
+       (re_match_2_internal): In emacs, set the locale variable multibyte
+       to 1, otherwise to 0.  New local variable target_multibyte.  Check
+       it to decide the multibyteness of STR1 and STR2.  Use
+       TARGET_CHAR_AND_LENGTH to fetch a character from D.
+       <charset, charset_not>: If multibyte is nonzero, check fastmap
+       only for ASCII chars.   Call bcmp_translate with
+       target_multibyte, not with multibyte.
+       <begline>: Declare the local variable C as `unsigned'.
+       (bcmp_translate): Change the last arg name to target_multibyte.
+
+       * search.c (compile_pattern_1): Don't adjust the multibyteness of
+       the regexp pattern and the matching target.  Set cp->buf.multibyte
+       to the multibyteness of the regexp pattern.  Set
+       cp->but.target_multibyte to the multibyteness of the matching
+       target.
+       (wordify): Use FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE instead of
+       FETCH_STRING_CHAR_ADVANCE.
+       (Freplace_match): Convert unibyte chars to multibyte.
+
+       * syntax.c (char_quoted): Use FETCH_CHAR_AS_MULTIBYTE to convert
+       unibyte chars to multibyte.
+       (back_comment): Likewise.
+       (scan_words): Likewise.
+       (skip_chars): The arg syntaxp is deleted, and the code for
+       handling syntaxes is moved to skip_syntaxes.  Callers changed.
+       Fix the case that the multibyteness of STRING and the current
+       buffer doesn't match.
+       (skip_syntaxes): New function.
+       (SYNTAX_WITH_MULTIBYTE_CHECK): Check C by ASCII_CHAR_P, not by
+       SINGLE_BYTE_CHAR_P.
+       (Fforward_comment): Use FETCH_CHAR_AS_MULTIBYTE to convert unibyte
+       chars to multibyte.
+       (scan_lists): Likewise.
+       (Fbackward_prefix_chars): Likewise.
+       (scan_sexps_forward): Likewise.
+

        * xfaces.c (QCfontset): New variable.
