+Subject: [PATCH] Recognize all wide unicode characters
+
+Type cast explicitly to (signed char) because sizof(char) can differ
+from sizof(int). Also do not quote bytes above 0x7F because we assume
+UTF-8 encoding.
+
+This should be fixed properly by UTF-8 to Unicode decoding but we
+need to recognize which encoding is in use before. How?
