we try to use PCRE2 to match UCS-2 encoding, i.e. UTF-16 without any
check for "broken" surrogates or any other invalid unicode. In UCS-2
encoding every character is 2 bytes and every 2-byte sequence is
accepted as a valid character.
Nevertheless we want unicode char properties to be considered, when
the code point at the corresponding position is valid UTF-16.
We recognized that the seem to get this behaviour, when we set the following:
PCRE2_UCP | PCRE2_NEVER_UTF | PCRE2_NO_UTF_CHECK
but we *do not set*
PCRE2_UTF
Is this correct? Does this have negative implications or undefined behaviour?
