The Fraktur fonts are missing from the standard math definitions. Currently, I have this kind of hack in t-amsl: \definebodyfont [17.3pt,14.4pt,12pt,11pt,10pt,9pt] [mm] [mc=eufm10 sa 1] \definebodyfont [8pt,7pt,6pt] [mm] [mc=eufm7 sa 1] \definebodyfont [5pt] [mm] [mc=eufm5] Basically, for what I can see, the problem is that mc= is not defined in the default typescript files. Adding it would be as simple as replicating the mi lines into mc lines, at least for computer-modern & similar, since the actual font used is the same. Could this please be done for the official distribution? -- Giuseppe "Oblomov" Bilotta
