I've now tried to move this app to Delphi 8 using the same DB and equivalent D8 controls.I thought that this would be an easy task as I'm lead to believe D8 is natively Widestring now so I thought the data would display correctly without any third-party components such as TNT, but its seems I'm wrong as the data is displaying incorrectly. So is DBExpress Unicode compatable or do I need to do some conversion of the data before I am able to display is properly? I understand the database holds all the data in UTF8 format so what must I do to convert this into a Widestring like the TNT components do? Many thanks, I'm a bit of a n00b with Delphi 8 so any tips are welcome (Jeez, what a project to learn Delphi 8 with!!!!!!)

In few words dbExpress does not support Unicode. Probably UTF8 will come through it (theoretically speaking). At least, i was able to get that from Oracle. Yes, D8 is .Net application, so it works in Unicode environment. But dbExpress is not. I think, D8 stupidly converts strings as ASCII->Unicode.
