[PD] request for objections: any2string -> unsigned char

Unicode would be great, if someone wants to implement that in Pd, I  
would fully support that.

As for the simple question of unsigned versus signed for any2string, I  
have never heard of using negative values for chars, so it makes  
perfect sense to me to use 0-255.  That'll will give at least the full  
latin charset.
