	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.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.

	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.

	cp->but.target_multibyte to the multibyteness of the matching
	target.

	FETCH_STRING_CHAR_ADVANCE.

	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.
