-/* A multibyte character is a short subsequence of a char* string,
-   representing a single wide character.
-
-   We use multibyte characters instead of 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,
-   5) portability, i.e. don't make unportable assumptions about wchar_t.
-
-   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.
-
-   mb_copy (&destmbc, &srcmbc)
-     copies srcmbc to destmbc.
-
-   Here are the function prototypes of the macros.
-
-   extern const char *	mb_ptr (const mbchar_t mbc);
-   extern size_t	mb_len (const mbchar_t mbc);
-   extern bool		mb_iseq (const mbchar_t mbc, char sc);
