+
+
BUGS
+
       The details of what constitutes an uppercase or  lowercase
+       letter  depend  on  the  current locale.  For example, the
+       default "C" locale does not know about umlauts, so no con-
+       version is done for them.
+
+       In some non - English locales, there are lowercase letters
+       with no corresponding  uppercase  equivalent;  the  German
+       sharp s is one example.
