- * mod_utf8_codepoint:
- * @s: string encoded in modified UTF-8
- * @n: maximum number of bytes to read from @s, if less than 6
- * @end: set to end of sequence on return
- *
- * Convert the modified UTF-8 sequence at the start of @s.  Modified
- * UTF-8 is exactly like UTF-8, except U+0000 is encoded as
- * "\xC0\x80".
- *
- * If @n is zero or @s points to a zero byte, the sequence is invalid,
- * and @end is set to @s.
- *
- * If @s points to an impossible byte (0xFE or 0xFF) or a continuation
- * byte, the sequence is invalid, and @end is set to @s + 1
- *
- * Else, the first byte determines how many continuation bytes are
- * expected.  If there are fewer, the sequence is invalid, and @end is
- * set to @s + 1 + actual number of continuation bytes.  Else, the
- * sequence is well-formed, and @end is set to @s + 1 + expected
- * number of continuation bytes.
- *
- * A well-formed sequence is valid unless it encodes a codepoint
- * outside the Unicode range U+0000..U+10FFFF, one of Unicode's 66
- * noncharacters, a surrogate codepoint, or is overlong.  Except the
- * overlong sequence "\xC0\x80" is valid.
- *
- * Conversion succeeds if and only if the sequence is valid.
- *
- * Returns: the Unicode codepoint on success, -1 on failure.
