Hello.

I would like to use this topic to know more about the DOA conversion by setting NoUnicodeSupport. I made a short test with a english and portuguese version of Windows, both seems to work with our common characters with accent.

There is a single mapping for all western languages? I'm specifically interested in english, spanish and portuguese.

With the Oracle XE 11.2, there is a fixed charset of AL32UTF8, so this is the only reason at the moment to deal with Unicode. I could be using ForceWideStringFields and changing all the TStringField - but with many hundred of thousands lines of code, it doesn't worth right now
