+.IP
+Because there are several RGB encodings in use,

+are unlikely to work reliably.
+As a trivial case, for example, one could define \fBRGB#1\fP

 asserts that ncurses must use Unicode values for line-drawing characters,
 and that it should ignore the alternate character set capabilities
 when the locale uses UTF-8 encoding.
