 .SH DESCRIPTION

-The function
-.B wctrans
-is used to obtain a handle to a mapping table that maps one set of wide
-characters to another. It returns an object of type
+.LP
+The functions
+.B wctrans()
+and
+.B wctrans_l()
+are used to obtain a handle to a table that maps one set of wide
+characters to another. They return an object of type
 .I wctrans_t
 which can be used with the functions
 .B towctrans()
 and
 .BR towctrans_l() .
 The valid set of classes that are available depends on the locale.
-Regardless of what locale is being used, the following names are always
-valid:
-
-.na
-.in +2

-.fi

+The following names are valid in all locales:
+.TP
+"tolower"
+Conversion from upper case to lower case characters.
+.TP
+"toupper"
+Conversion from lower case to upper case characters.
