It's not a show stopper.
However it needs to be included in any benchmarking to compare candidate
engines.
I.E. compare the time to evaluate a regexp on a QString.
If the engine API is UTF16, then QString::constData can be used with no
additional cost.
I suspect the conversion cost is mainly in the memory allocation.

An UTF16 API is required for the engine though, as all QStrings are UTF16.
