"I personally think UTF-8 is a better overall design though."
Unicode Technical Note #12 by The Unicode Consortium apparently disagree,
recommending UTF-16 for Processing.
http://unicode.org/notes/tn12/
The major claim in the TN is that Unicode is optimized for UTF-16. The rest of
the argument looks like a VHS (everyone is using it i.e. UTF-16) versus Beta argument.
So who's right? My personal view is that whilst they are the *Unicode Consortium*,
I have great difficulty in accepting UTF-16 as the one-and-holy encoding.
FWIW, there was a subthread during a discussion about the ordained features of
programming languages on LtU a while back.

What Are The Resolved Debates in General Purpose Language Design?
Its a long discussion so easier to search for UTF or Unicode on the page if you're interested.
