I'm glad you liked it!

I cannot estimate how feasible a port would be --- since I don't use VC6
regularly. I'll try to do something after review -- hopefully with some
luck.

I have to consider this. An obvious approach would be to add template
parameter to every class, telling which char type to use. So investigation
is needed to find alternatives --- making everything a template would
conflict with ability to compiler everything as shared library.

This is planned feature --- several other persons expressed a desire for it.
