+Subject: [PATCH] Fix unicode character printing (#112)
+
+* Fix unicode character printing
+
+Fix several issues that prevented it from working
+
+  * link to the wide-character version of ncurses
+  * define NCURSES_WIDECHAR
+  * use a function that can print wide characters
+  * fix the character range. I don't know what the original was supposed
+    to be, but half-width kana (which is what the movie reportedly used)
+    was not at that range.
+
+* Fix half-width kana character range
+
+I'm not very familiar with katakana, but I think the extra characters I
+was using are punctuation or other marks. So let's remove them. Note
+that this is the same range space-pagan is using.
