Validation can be done by removing PCRE_NO_UTF8_CHECK option. If your input is
big this can take long time however. Furthermore if you perform a match
multiple times against the same subject string the checking is done the same
number of times which is not performance efficient.
(Note: next release of pcre2 will support invalid utf subject string when JIT
compiling is used)
