-In PCRE, by default, \ed, \eD, \es, \eS, \ew, and \eW recognize only ASCII
-characters, even in a UTF mode. However, this can be changed by setting the
-PCRE_UCP option.
+By default, \ed, \es, and \ew match only ASCII characters, even in UTF-8 mode
+or in the 16- bit and 32-bit libraries. However, if locale-specific matching is
+happening, \es and \ew may also match characters with code points in the range
+128-255. If the PCRE_UCP option is set, the behaviour of these escape sequences
+is changed to use Unicode properties and they match many more characters.
