- The <STRONG>use_legacy_coding</STRONG> function is an extension to the
- curses library. It allows the caller to change the result
- of <STRONG>unctrl</STRONG>, and suppress related checks within the library
- that would normally cause nonprinting characters to be
- rendered in visible form. This affects only 8-bit charac-
- ters.
