I don't have a strong opinion on this, but I'd say stick to using the  
arrays how they are represented in Pd rather than how they are  
implemented in C.  This will keep the library flexible and  
maintainable.  It seems to me that this should something that is a  
more functionality.  I guess that is Martin Peach's approach with his  
string/blob patch.

And by the way, since I am in middle of rewriting the GUI, let me know  
what I can do to make sure that this stuff is well supported in the  
GUI.  Tcl is fully UTF-8 as far as I know.  It would be nice to have  
pd be UTF-8 as well.  I don't really have a good idea how far pd is  
from being UTF-8.
