Yes, my comment was in response to a comment about UTF-32 as
pertaining to an internal encoding. I'd only use UTF-16 if the APIs I
used required it, and the conversion could be done at the interface
(for example in a fascade). What interests me is if there's a good
reason to use UTF-8 internally and give UTF-32 the same treatment as
UTF-16, or vice versa. I do find the simplicity of a fixed-width
encoding alluring.

By the way, I disagree with Peter's assessment that, "you rarely, if
ever, need to access the Nth character," but I will gladly cede that
this depends on your problem domain.
