Hi Paul,

This seems to be working quite nicely, after playing around for a bit. A fe=
w=20
of my test files were throwing "Iconv::InvalidCharacter" errors on some=20
strings, but when I change the "(s+' ')" to "(s)" it works fine. Then, of=20
course, the strings that originally worked start throwing the error. So, I =
do=20
this:

begin
  textString =3D @ic.iconv(data+' ')[0..-2]
rescue
  textString =3D @ic.iconv(data)[0..-2]
end

Yesir, I am really just mashing code together until I see the results I am=
=20
looking for...

I wonder though, the docs lead me to believe the iconv library is UNIX only=
=2E=20
Is this true? I really need a cross-platform solution, but don't have a win=
32=20
box to try on...

Thanks very much,

> Paul.
