Would adding a turbo charger to a wankel rotary engine eliminate most of the problems associated with them?

I was reading up on these engines and many of the cons for them seem to be sealing, efficiency and emissions. The article I read stated that the emissions are a problem due to the un-burned  hydrocarbons expelled in the exhaust, now if a turbo charger was added and this hydrocarbon rich exhaust was mixed with air and fed into the engine intake wouldn't this not only improve efficency but also significantly reduce emissions?
If anyone knows of an instance where this has been implemented or can shed some light on this, it would be much appreciated, Thanks!

That is not how a turbocharger works. Exhaust gasses are not re-introduced into the intake system. The flow of the exhaust turns an impeller that compresses the fresh air in the intake system.

Mazda did, in fact, ship several turbocharged Rx-7 models.  The rotor seal failures were fixed in the 13B engines design in the early 1980s. Fuel efficiencies improved with computerized engine management, improved ignition systems, and finally the side-draft intake and exhaust ports introduced in the Rx-8. The hydrocarbon particulates in the exhaust are not typically unburnt fuel -- they come from the motor oil injected into the rotor chambers to lubricate the rotor seals. Further research into ceramics or micro materials may overcome the rotor seal lubrication issue.
