Thanks! I've seen that you've also checked in my typecodes addition to
arraymodule.c Do you think it's worth backporting to 2.6?

The table
http://www.python.org/dev/peps/pep-3118/#additions-to-the-struct-string-syntax
isn't exactly clear to me. I *guess* 'u' means UCS-2 on all platforms
and builds of Python - even UCS-4 builds - and 'w' is only available on
wide builds. I suggest that you place emphasis on the size to make the
table unambiguous. I know that I'm nit picking but documentation should
be crystal clear. ;)

If I'm correct with my assumption about 'u' and 'w' your suggestion of a
native 'U' could become in handy.
