Should we get rid of libnpt.so ?

[Kelly O'Hair]

Keep in mind that there are 3 sets of sources for npt, share/npt, solaris/npt and windows/npt
it is quite platform specific, using iconv libraries on solaris/linux, and multi/wide byte strangeness on windows.

So it wasn't just the functionality that drove it into it's own library, the implementation of how you have to deal with utf8 in a native world made it ugly, and isolating it was the only way to put lipstick on this pig.

You need to look at all the code before you start doing cut&paste on the source.
