« I suppose the problem is that the use of a rule (as opposed to a

having this glyph somewhere could however be usefull for other
programms (i remember that it had been said that everything non
tex-specific could be shared with the outer world)? This means that
this dash could be usefull in MSP where the `normal' radical sign
