Strictly speaking, ";" comes to mind. "?" is another, or even "&" or "/".

Although looking at it in the context of the file format, EMF (not to be 
confused with EML) is a graphics format and i dont think should ever 
take input (but i may be wrong, never checked).

So that takes "?" out of the equation. There are probably more that i 
have missed.
