+=head1 ENCODING
+
+Since Redis knows nothing about encoding, we are forcing utf-8 flag on all data received from Redis.
+This change is introduced in 1.2001 version.
+
+This allows us to round-trip utf-8 encoded characters correctly, but might be problem if you push
+binary junk into Redis and expect to get it back without utf-8 flag turned on.
