Nov 10, 2015 at 8:47 comment added Robert Seifert Sounds like a good idea, unfortunately I'm not familiar enough with core latex to get work, I wouldn't know where to start. I'm about to post a follow up question, where your comment maybe could be an answer, I post a link her ein some minutes.
Nov 10, 2015 at 8:42 comment added user4686 yes. And also \mathfrak {\foo} is not that much better than \fooup... as an aside with pxgreeks one can use \otheralpha, \otherGamma... to get the italic if the default is upright and vice versa. Last comment: except if you want a macro with \mathrm {#1} I think the ...up mark-up is clearer. With legacy fonts, \mathrm switches to a font, it is not a command to get "upright". Thus, one should rather define a command \upright which would do all the preliminary works, like switch to the "operator" family, and treat all math symbols which do not obey the switch.
Nov 10, 2015 at 8:15 comment added Robert Seifert works with lualatex as well, but is however not really a solution as it requires X_{\mathrm{\delta d}} to be splitted up in X_{\mathfrak{\delta}\mathrm{d}} because greek and latin behave not the same.
