What do you intend to do with that uint32 value at this moment, where BString
or cout is not yet supporting such a type of parameter?
And how would this help e.g. to invert a UTF8 text?

Why that? I proposed a routine working at a given index inside a BString?
So there will be just an amount of operations corresponding to the length
of the symbol at index. So where is the complexity?

Not without having also a wide char kind of type.
I tried to propose a very simple BString extension for this moment.
