Weird... I sent this over a month ago, and was a bit puzzled as to why it didn't appear on the list. Has it been waiting for a moderator to release?

Hello cafe,
(Following up on my own optimisation question, and Duncan's advice to look at http://darcs.haskell.org/ghc/compiler/utils/Encoding.hs)
If you want to look at some existing optimised UTF8 encoding/decoding code then take a look at the code used in GHC:

I took a look at the UTF8 decoder in GHC. This inspired me to write one that also used unboxed types directly. Pleasingly, it goes like a cut cat, and uses far less space than the naive version, but it's not portable, which is a bummer. ...
