Hello, i need to use some different Codepages to display russian or czechian text. But the problem is, that the database (Sybase Anywhere) needs to use the same codepage to be able to store those special characters. This is a problem because i need to install the right database for the destination-language... but what, if the user likes to use two languages? I've seen, that i can have german umlauts on a czechian Win2k. But i can't have german umlauts on a russian Win2k. So the question is: - is there a single codepage which supports german umlauts, czechian special characters and russian too? Or a least one codepage for german/russian and one for german/czechian? - is there a list (overview) available which explains (in detail?) which characters are available on each codepage? I think a big solution would be, to make everything with unicode - but i think it's not possible to change a whole set of applications (10+ EXE-Files, 10+ OCX, DLLs, etc) to unicode (we're still on Delphi3 for the main application and Delphi5/7 for new OCX/DLLs). (i mean, it not just the visual controls which has to be changed - which is a big problem because DevExpress doesn't support unicode and we are using their grid... but what about internal functions that are working with String-Functions (pos, trim, sort, etc.) and what about constants that are in the sourcecode - Delphi itself doesn't support unicode) And as far as i know it is not possible with the Sybase Anywhere Database to work with unicode?

Unicode is the only way to achieve three languages at the same time. IIRC, Sybase Anywhere supports utf-8.

Hi Boris, Quote: - is there a list (overview) available which explains (in detail?) which characters are available on each codepage? Sure, going via my Unicode site (www.delphi-unicode.net) you will get the link: Codepages & Co, http://czyborra.com/charsets/codepages.html. Quote: And as far as i know it is not possible with the Sybase Anywhere Database to work with unicode? Like Francisco I would also recommend take the UTF-8 route, which allows to stay with normal strings in the database and even in the applications (since ASCII is part of the UTF-8 encoding), but you cannot use the new characters then, of course. When times come to add a new language then you can explicitely convert the new app/dll to use Unicode (actually UTF-16), but you have to use Unicode aware controls then (I heard of some people who switched from DevEx Grid to my Virtual Treeview ). You can even start with TRichEdit, which supports Unicode, but you have to add some functionality to get Unicode in and out.

Quote: currently i'm not aware what utf-8 really is and how it works... if you have some good links for informations on this topic (utf-8 and Delphi/Sybase Anywhere) it would be great It is not exactly easy in your case, since using UTF-8 basically means you have to deal with Unicode, which is not something you currently want to do.
