ASCII in C++ Builder XE

I want to make an application in Embarcadero C++ Builder XE totally in ASCII but C++ Builder XE's VCL are now UNICODE base.

Anybody has any kind of idea that how can I do that

If any Preprocessor Directives or anything else

I want to use sqlite3 as a backend, but all the code examples I see use ASCII and the Unicode doesn't work for me.

I've been Googleing it for couple of days but didn't find any s开发者_StackOverflow社区olution

You can use the AnsiString string classes, the different VCL strings convert without problems between each other. If you have a UnicodeString and want to access the character array as regular 8 bit characters instead of the wchar_t datatype you can use the t_str() function instead of the c_str().

I would however suggest that you looked at the UTF8String class, it is one of the most interesting of the string classes because it is backwards compatible with 7-bit ASCII as well as giving you the possibility of supporting international characters.
