+Subject: [PATCH] Ignore processing variable files with unsupported encoding
+ (RhBug:2141215)
+
+This issue could be seen for example when there are some temporary files stored by text editors in the `/etc/dnf/vars` folder. These files could be in the binary format and causes `UnicodeDecodeError` exception to be thrown during processing of the var files.
