Sorry i got a couple of questions.

is it safe using @ ?
I know various chars like # and & couldn't be used.
i have a funny feeling @ is used for something, iirc pointers so should not
be used this way.

what would be safe chars to use?

Tilde maybe?  but i could not find the RS_CODE for ~ tilde
Semicolon looks unused

Thanks in advance
