Message        A UCN escape sequence was recognized, but there was
                no translation for it into the current codeset.  The
                escape sequence will be used verbatim.

 Description    A Universal Character Name (UCN) escape sequence was
                recognized, but there was no translation for it into
                the current codeset using the iconv library routine.
                The complete escape sequence itself, including the
                backslash, will be used in the object module.

 User Action    Make sure your locale is set at compile-time to use a
                codeset for which a converter from UCS-4 is
                available, and which supports all of the characters
                that are expressed as UCNs in your program.
                Alternatively, change your code to avoid the use of
                UCNs, e.g.  using hexadecimal escape sequences.
