The biggest problem is that sys_gui() and sys_vgui() as it is being used 
by all of PureData's externals does not prepare special characters at all, 
and the backslash and braces are special characters in Tcl, the language 
used in the user-interface part of PureData; this means that any use of 
those special characters is ambiguous and confuses Tcl, leading to all 
sorts of weird things such as objects being partially drawn, or worse.
This is why those three characters \{} are disabled.

This should be the first topic in the upcoming 4th online PureData 
developers meeting, which will be next Friday. I'll announce it on the 
pd-dev mailing-list today. I have yet to prepare the list of topics we 
will discuss, which is why I haven't announced it officially yet.
