IMHO PuTTY's default behaviour of pasting the clipboard's contents on right click is really annoying and unexplainable; neither native Windows apps or Unix xterms work like that. At our university we use IRC (via SSH+Screen+irssi mostly) for communication and every year I see over a dozen of people tripping into that.
Also, the default encoding was changed to UTF-8 only quite recently - IMO that should have been done much earlier.

That's because it's middle-click instead of right-click in X. But windows traditionally did not have 3-button mouses, so right-click it is. I use middle-click to paste several times per hour.
