+2009/06/09: UNICODE ISSUES
+    1. some double-width characters don't work right (see japanese.txt)
+
+    2. need input methods for unicode characters
+
+    3. regexes need to be made unicode-aware
+
+    4. make ad-hoc strings in application u'' strings
+
+    5. handling terminal output type (utf-8, latin-1, ascii)
+
 2009/06/09:
     1. many of the dir-mode methods need better names, to make it clear they
     aren't general purpose.
