FBClient is not required to break external API

Even if, for example in FB3, new version of wire protocol introduced, making Unicode or charset specification madatory, that would not break Delphi applications, provided that FBClient would make it's work of translating wire protocol to used DLL API correctly, including transparent charset changes if needed.

The fact that BLOBs can get around such limitations would lead to "VARCHAR too" wishes, and they would be reasonable :-)
