Hi, Hans, Thank you for the great works. But there is still a problem when
I test a more complicated file which is attached below. In this file,
both \bf and \bi give the same font lmroman10-bold.

I guess the reason is that I use the same Chinese font
AdobeHeitiStd-Regular for both SerifBold and SerifBoldItalic. But this
cannot be avoided since Chinese fonts have much fewer typefaces than
English fonts.

Would you give some suggestions to solve this problem? Thanks a lot.

    \definefontsynonym [zhserifbolditalic][AdobeHeitiStd-Regular][features=zh]

    \definefontfallback[serifwhatever][lmroman10-regular][0x0000-0x0400][force=yes]

\stoptypescript

\starttypescript[myfont]
    \definetypeface[myfont][rm][serif][zhfont]
\stoptypescript

\usetypescript[myfont]

\starttext
