 Description:
 Return current locale's character encoding.
 
+Notice:
+If your package's tests make use of the locale_charset() function directly or
+indirectly, you may need to define the CHARSETALIASDIR environment variable,
+so that "make check" works before "make install". In Makefile.am syntax:
+TESTS_ENVIRONMENT += @LOCALCHARSET_TESTS_ENVIRONMENT@
