-/*************************************************
-*         Validate a UTF-16 string                *
-*************************************************/
-
-/* This function is called (optionally) at the start of compile or match, to
-check that a supposed UTF-16 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.
-
-From release 8.21 more information about the details of the error are passed
-back in the returned value:
-
-PCRE_UTF16_ERR0  No error
-PCRE_UTF16_ERR1  Missing low surrogate at the end of the string
-PCRE_UTF16_ERR2  Invalid low surrogate
-PCRE_UTF16_ERR3  Isolated low surrogate
-PCRE_UTF16_ERR4  Unused (was non-character)
-
-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-16 string
-               > 0    otherwise, setting the offset of the bad character
