+What steps will reproduce the problem?
+I don't know exactly when it started
+
+What is the expected output? What do you see instead?
+When I run git annex unused I get
+
+unused . (checking for unused data...) (checking master...) git-annex: Cannot decode byte '\xb4': Data.Text.Encoding.decodeUtf8: Invalid UTF-8 stream
+
+Most likely I have added some file with a strange encoding that git-annex can't decode. The problem is that the unused process aborts because of this.
+
+What version of git-annex are you using? On what operating system?
+ 3.20120522, Debian testing
+
+Please provide any additional information below.
