Having printed the mma symbol fonts, I have the following remarks: a) On integrals: The mma fonts contain a class of integrals and other big operators larger than \displaystyle. For a moment I played with the thought of an e-TeX proposal \bigdisplaystyle (appropriate, if there is a displaystyle fraction in the ``argument'' of a big operator) but discarded it soon. The reason for discarding the thought was, that the argument of a big operator cannot be detected automatically. Maybe setting up the integrals as delimiters can make the largest size available ... I will have to think further about this approach. b) On bullet-like symbols There are three sizes of bullet-like symbols (squares, circles) in the mma fonts. IMHO a good choice, the smallest being appropriate as binary operators, the largest as miscellanous symbols. c) A special symbol: The is a ``mouth'' like symbol near \approx in the mma fonts, consisting of smallfrown over smallsmile. What is it used for? d) \de, \ee, \ie There are special symbols for the d in differentials, the base of the natural logarithm and the square root of -1. However, Wolfram's designs are just plain ugly and not supported anywhere else (mathroman type being the design of choice). e) Other I found the capital Epsilon (like african open E) also in the mma fonts. Worth considering for the encoding, I think. --J"org Knappen
