The application can lock out the use of \C by setting the
PCRE2_NEVER_BACKSLASH_C option. It is dangerous because it may leave the

\C is dangerous because it may leave the current matching point in the middle
of a UTF-8 or UTF-16 character. The application can lock out the use of \C by
setting the PCRE2_NEVER_BACKSLASH_C option. It is also possible to build PCRE2
with the use of \C permanently disabled.
