Not assume! Developer will be able set it using

        db.IOEncoding = "UTF8"

 then RevDB always assume it get UTF8 strings?

Right. The same we can do for OUR API also.

Right now no. but if we add into game
        db.IOEncoding = "UTF8"

Then this can start work.

We have not work yet on this problem, because Mark have told that in 2.8
Revolution will allow us use UTF in externals.

Trevor. Everything is simple.

* now Valentina get char* string and think this is MacRoman on mac.,

* if you will change that using
            db.IOEncoding = "UTF8"

Then Valentina will think that each string you give it is UTF8.

I think quite logical.

Of course it is cool if future Revolution will allow us just send wchar_t
