Hi Hans VdM and Wolfgang, It is true that naming a variable PYR, even in plain TeX, as shown below, gives rise to an ugly mathematical symbol since there is a certain distance between the « Y » and the « R » with math italic: http://dl.dropbox.com/u/4316076/spacing-plain.pdf The problem may be the bounding box of « Y ». However, I think that in the example given by Hans VdM in mkiv, there is another, more important, issue which is the way the commas are treated between the variables Q, Y, N, P, Y, Z in math italic. Please compare the following outputs, one obtained with mkii and the other with mkiv: http://dl.dropbox.com/u/4316076/spacing-mkii.pdf http://dl.dropbox.com/u/4316076/spacing-mkiv.pdf I think that this is a big issue in typesetting maths with mkiv since punctuations are treated in an incorrect way. Best regards: OK PS: Sorry for the delay… yesterday this message was rejected when sent with the attached PDFs, because it was over 64Kb. On 13 mars 2011, at 13:16, Hans van der Meer wrote:
It might be that I am missing something here. But I don not understand why in the math expression below the spacing behind the letters is different. With this behaviour it seems impossible to name a variable PYR and have it typeset as such.
