/*************************************************
*         Validate a UTF-8 string                *
*************************************************/

/* This function is called (optionally) at the start of compile or match, to
check that a supposed UTF-8 string is actually valid. The early check means
that subsequent code can assume it is dealing with a valid string. The check
can be turned off for maximum performance, but the consequences of supplying an
invalid string are then undefined.

Originally, this function checked according to RFC 2279, allowing for values in
the range 0 to 0x7fffffff, up to 6 bytes long, but ensuring that they were in
the canonical format. Once somebody had pointed out RFC 3629 to me (it
obsoletes 2279), additional restrictions were applied. The values are now
limited to be between 0 and 0x0010ffff, no more than 4 bytes long, and the
subrange 0xd000 to 0xdfff is excluded. However, the format of 5-byte and 6-byte
characters is still checked.

From release 8.13 more information about the details of the error are passed
back in the returned value:

PCRE_UTF8_ERR0   No error
PCRE_UTF8_ERR1   Missing 1 byte at the end of the string
PCRE_UTF8_ERR2   Missing 2 bytes at the end of the string
PCRE_UTF8_ERR3   Missing 3 bytes at the end of the string
PCRE_UTF8_ERR4   Missing 4 bytes at the end of the string
PCRE_UTF8_ERR5   Missing 5 bytes at the end of the string
PCRE_UTF8_ERR6   2nd-byte's two top bits are not 0x80
PCRE_UTF8_ERR7   3rd-byte's two top bits are not 0x80
PCRE_UTF8_ERR8   4th-byte's two top bits are not 0x80
PCRE_UTF8_ERR9   5th-byte's two top bits are not 0x80
PCRE_UTF8_ERR10  6th-byte's two top bits are not 0x80
PCRE_UTF8_ERR11  5-byte character is not permitted by RFC 3629
PCRE_UTF8_ERR12  6-byte character is not permitted by RFC 3629
PCRE_UTF8_ERR13  4-byte character with value > 0x10ffff is not permitted
PCRE_UTF8_ERR14  3-byte character with value 0xd000-0xdfff is not permitted
PCRE_UTF8_ERR15  Overlong 2-byte sequence
PCRE_UTF8_ERR16  Overlong 3-byte sequence
PCRE_UTF8_ERR17  Overlong 4-byte sequence
PCRE_UTF8_ERR18  Overlong 5-byte sequence (won't ever occur)
PCRE_UTF8_ERR19  Overlong 6-byte sequence (won't ever occur)
PCRE_UTF8_ERR20  Isolated 0x80 byte (not within UTF-8 character)
PCRE_UTF8_ERR21  Byte with the illegal value 0xfe or 0xff

Arguments:
  string       points to the string
  length       length of string, or -1 if the string is zero-terminated
  errp         pointer to an error position offset variable

Returns:       = 0    if the string is a valid UTF-8 string
               > 0    otherwise, setting the offset of the bad character
