I see.

Does they compress dbs when move them?
If yes, I think UTF16 must have very good compression.

Jon, in fact we will do this.

V4RB get string from RB in UTF8,
And it MUST convert it to UTF16 internally.
And may be on write down to disk convert into UTF8.

This is why it can be better keep db file always in UTF16 also.

Well, IBM guys say that UTF8 -> UTF16 conversion is quite fast.

Java also in UTF16 I think,
As well a MacOS X and Windows self.
