+/* A multibyte character is a short subsequence of a char* string,
+ representing a single 32-bit wide character.
+
+ We use multibyte characters instead of 32-bit wide characters because
+ of the following goals:
+ 1) correct multibyte handling, i.e. operate according to the LC_CTYPE
+ locale,
+ 2) ease of maintenance, i.e. the maintainer needs not know all details
+ of the ISO C 99 standard,
+ 3) don't fail grossly if the input is not in the encoding set by the
+ locale, because often different encodings are in use in the same
+ countries (ISO-8859-1/UTF-8, EUC-JP/Shift_JIS, ...),
+ 4) fast in the case of ASCII characters.
+
+ Multibyte characters are only accessed through the mb* macros.
+
+ mb_ptr (mbc)
+ return a pointer to the beginning of the multibyte sequence.
+
+ mb_len (mbc)
+ returns the number of bytes occupied by the multibyte sequence.
+ Always > 0.
+
+ mb_iseq (mbc, sc)
+ returns true if mbc is the standard ASCII character sc.
+
+ mb_isnul (mbc)
+ returns true if mbc is the nul character.
+
+ mb_cmp (mbc1, mbc2)
+ returns a positive, zero, or negative value depending on whether mbc1
+ sorts after, same or before mbc2.
+
+ mb_casecmp (mbc1, mbc2)
+ returns a positive, zero, or negative value depending on whether mbc1
+ sorts after, same or before mbc2, modulo upper/lowercase conversion.
+
+ mb_equal (mbc1, mbc2)
+ returns true if mbc1 and mbc2 are equal.
+
+ mb_caseequal (mbc1, mbc2)
+ returns true if mbc1 and mbc2 are equal modulo upper/lowercase conversion.
+
+ mb_isalnum (mbc)
+ returns true if mbc is alphanumeric.
+
+ mb_isalpha (mbc)
+ returns true if mbc is alphabetic.
+
+ mb_isascii(mbc)
+ returns true if mbc is plain ASCII.
+
+ mb_isblank (mbc)
+ returns true if mbc is a blank.
+
+ mb_iscntrl (mbc)
+ returns true if mbc is a control character.
+
+ mb_isdigit (mbc)
+ returns true if mbc is a decimal digit.
+
+ mb_isgraph (mbc)
+ returns true if mbc is a graphic character.
+
+ mb_islower (mbc)
+ returns true if mbc is lowercase.
+
+ mb_isprint (mbc)
+ returns true if mbc is a printable character.
+
+ mb_ispunct (mbc)
+ returns true if mbc is a punctuation character.
+
+ mb_isspace (mbc)
+ returns true if mbc is a space character.
+
+ mb_isupper (mbc)
+ returns true if mbc is uppercase.
+
+ mb_isxdigit (mbc)
+ returns true if mbc is a hexadecimal digit.
+
+ mb_width (mbc)
+ returns the number of columns on the output device occupied by mbc.
+ Always >= 0.
+
+ mb_putc (mbc, stream)
+ outputs mbc on stream, a byte oriented FILE stream opened for output.
+
+ mb_setascii (&mbc, sc)
+ assigns the standard ASCII character sc to mbc.
+ (Only available if the 'mbfile' module is in use.)
+
+ mb_copy (&destmbc, &srcmbc)
+ copies srcmbc to destmbc.
