The code exists, but I don't have it. It's part of the QCharIterator work I 
did while at Nokia but never published, so I don't have rights to that code 

I'm sure I put it in the codereview tool before I left so it would be 
opensourced some day.

XML parsing? no, I doubt.

JS engine? Yes, a lot. That's why JavaScriptCore is being replaced with V8 

QRegExp? don't try. The RE backend needs to be replaced.

C++ being a dependency is a very, very weak argument. There are lots of GNOME 
applications using gtkmm, pangomm, etc. C++ is present in most/all systems 
anyway, so it's not a dependency.

The argument they may have is to Qt as a dependency, but as I said, that's not 
an argument for me. Qt being present and loaded into memory is baseline.

All problems with bindings can be solved.
