ChangeLog

@@ -262,7 +262,9 @@ CVS code -
 - winio.c:
   get_word_kbinput()
 	- Limit the input word to hexadecimal FFFD instead of FFFF, as
-	  FFFE and FFFF are invalid Unicode characters. (DLR)
+	  FFFE and FFFF are invalid Unicode characters, rename variables
+	  word and word_digits to uni and uni_digits, and rename to
+	  get_unicode_kbinput(). (DLR)
   display_string()
 	- Instead of using parse_mbchar()'s bad_chr parameter, use
 	  mbrep() to get the representation of a bad character. (DLR)
