More precisely I meant that FB won't ever be giving us UTF-16, so if we want unicode from Firebird it will be UTF-8. Delphi has "AnsiString" type with a codepage attribute that will probably support most of what people wanted regarding the handling of specific character sets from the database ... though I suspect it will usually be simpler just to ask FB for UTF-8 and be done with it. None of which is a big deal, it's just a matter of NOT using "char" and "PChar" in the interface elements of the API, because in Delphi 2009+ these are UTF-16. Use AnsiChar and PAnsiChar and this will work with both Delphi and FPC. >> provide both Delphi and FreePascal support in example code will >> need to take care to use specific types, like UTF8String rather >> than just String.
