Such people should retrain if they want to switch to Unicode using
some instructions how to convert your application. If they do not
want, they should stay with Ansi. There is no automatic switch your
application to Unicode.

If you assume MyChar is 8-bit, then you are using Ansi. MyChar should
be the same type as MyString. At best it could be UTF-32 encoded
32-bit value representing character but then you may lose info about
how the character is composed, unless you normalize. Plus in future
32-bit may be not enough.
