I've got the values from the output of "mtxrun --script fonts --list
--all --pattern=xxx" (and compared with the name/style values in
Fontforge), so I don't understand why "spec:roman1" works, but
"spec:italic1" doesn't.

Additionally, what I think must be a bug is that
"italicfont=file:xxxitalic1, boldfont=file:xxxroman2" works but stops
working if I add "regularfont=spec:roman1":

\definefontfamily[xxxface][serif][xxx][regularfont=spec:roman1,
italicfont=file:xxxitalic1, boldfont=file:xxxroman2]

Maybe if one of the values uses the "spec:" selector, all the values
are treated as spec values despite the "file:" selector given?

Thanks, this works.  For some reason, "tf=" works, but "regularfont="
doesn't.

And by the way, this works:
\definefontfamily[leitura][serif][Leitura News][regularfont=spec:roman2]

and this doesn't work:
\definefontfamily[leitura][serif][Leitura News][tf=spec:roman2]

So in some cases only "regularfont" seems to work, and in some cases
only "tf".

Kind regards,
Joshua
