My Delphi win32 app uses TtntDBEdit to display and get unicode chars, this app also uses MyDAC (4.3) or MyComponentes (4.4 SciBit) components for connection. My problem is that I cannot display nor store correctly these japanese chars from/to MySQL server. Fields recovering with Delphi to use ADO with MS-Access are TWideStringField type, but this doesnot happen with MySQL. Any suggestion to resolve this? Thanks.

AFAIK there is no OLE DB provider for MySQL. How are you accessing it? Via ADO+ODBC? Using the .NET provider for MySQL? -- Best regards :) Guillem Vicens Meier Dep.

To use ADO you need either an OLE DB provider or an ODBC provider (if you use ADO+ODBC) or a ADO.NET provider (when programming in .NET). That's the origin of my question. I haven't used MyDAC but I know they support Unicode so that should not be the problem (unless there is some bug). Maybe you have to configure specifically the MyDAC components to allow Unicode? -- Best regards :) Guillem Vicens Meier Dep.
