[Encode] piconv lints

[Dan Kogai]

jhi,

  Thank you so much for 3 consecutive patches.  All applied 
successfully.  Combined result right after the sig.
   BTW, How do you say "thanks" in Suomi?  I tried to cheat via 
http://www.freedict.com/ but gave me no clue (there were 10 listed under 
Japanese!)
