Well, I use VirtualStringGrid with millions of nodes in my program
and it works like a charm (with UTF8) on Windows.

When I log my whole hard disk multiple times the the logging comes
totally from memory.
There is no hard disk movement at all.
Still there is no difference.

It is the world of exact such thinking.
People are creating this.
It's not a law of nature.

That's nonsense.
The *need* to convert between encodings should be restricted to just
that: Only when it is needed.
We should never force people (neither programmers nor users nor anyone)
to juggle encodings.
The aim should be to *reduce* conversions not to increase them.
