_TCHAR * argv to char

Hello,

I want to transform the input argument to a char.

For example, there is a 'A' in my argv[3], in the argument, and I want to use it as a char in my main program.

BTW, I use unicode and I have to use it.
I have already tried to use

char(argv[3]); this does not work

then
char tmp[2];
sprintf(tmp, "%s", argv[3]);
this does not work as well

argv[3][0] is the first char of the string.
argv[3] is the whole string.
