I'd second your opinion about the interface, but regarding speedup and
memory fragmentation makes me think.

For speed I'd need some hints, what technique would be faster/fastest?

And for memory fragmentation: avoiding Copy could be done by using
pointers running over the input string, or is there an even better
approach?

that' ;)
