On the other hand, you can use something like QT, except that judging from
claims made by the KDE 4 developers, QT has a bunch of Unicode-related bugs
which they refuse to fix (the one which keeps biting me is that the
application will suddenly decide I am typing right-to-left, and everything I
type shows up in redro gnorw eht. Only restarting the application fixes it.
I don't think that choosing UCS-2 only is any worse than any other
application feature like "support only jpegs, not every obscure image format
GIMP supports" or "choose to use floating point maths instead of some
numeric type with unlimited precision". You are free to make whatever trade-
offs you like, and your users are free to use another application :-)
