properly check for ICU status so known tags get actually recognized

nIcuErr after the second RegexMatcher::find() call was
U_STRING_NOT_TERMINATED_WARNING hence a check for U_ZERO_ERROR failed
and a content string of "foo <emph>bar</emph> baz" became
"foo <emph>bar&lt;/emph&gt; baz" which later provoked a missing ending
tag error.

This should had used U_SUCCESS(nIcuErr) instead and only worked by
chance. Apparently the warning wasn't issued in earlier ICU versions and
only introduced with 55 or 56.
