 function returns zero if the character tests false and
 returns non-zero if the character tests true.
+.Sh COMPATIBILITY
+The
+.Bx 4.4
+extension of accepting arguments outside of the range of the
+.Vt "unsigned char"
+type in locales with large character sets is considered obsolete
+and may not be supported in future releases.
+The
+.Fn iswgraph
+function should be used instead.
