Error Howto convert Ascii -> UTF-8 & back C++
While working with russian text under FreeBSD&MySQL I need to convert a string from MySQL to the Unicode format.
I've just started my way in C++ under FreeBSD , so please explain me how can I get ascii code of Char variable and also how can i get a character into variable with the specified ascii code.

I know that in Basic there is a commands for that : Asc() and Chr(), is there variant of this on C++?

I'm not sure if this is what you're asking, but you can cast a char to an int.

char c;
c='A';
printf("%d \n", (int) c);
