- Calculate the length of the initial segment of 'str' which consists
- entirely of characters not in 'reject'.
-
- @param cs Pointer to charset info.
- @param str Pointer to multi-byte string.
- @param str_end Pointer to end of multi-byte string.
- @param reject Pointer to start of single-byte reject string.
- @param reject_length Length of single-byte reject string.
-
- @return Length of segment of multi-byte string that doesn't contain
- any character of the single-byte reject string or zero if an
- invalid encoding of a character of the multi-byte string is
- found.
-
- @note The reject string points to single-byte characters so it is
- only possible to find the first occurrence of a single-byte
- character. Multi-byte characters in 'str' are treated as not
- matching any character in the reject string.
- This method returns zero if an invalid encoding of any character
- in the string 'str' using charset 'cs' is found.
-
- @todo should be moved to CHARSET_INFO if it's going to be called
- frequently.
-
- @internal The implementation builds on the assumption that 'str' is long,
- while 'reject' is short. So it compares each character in string
- with the characters in 'reject' in a tight loop over the characters
- in 'reject'.
