All, I am running Miktex on Windows. I took my YandY lucida fonts (pfb and afm files) and put them in a temporary directory, f:\temp\fonts\lucida on my system. I then ran: texfont --fontroot=f:\localtexmf --sourcepath=f:\temp\fonts\lucida --vendor=yandy --collection=lucida --makepath --install I then added the following line to pdftex.cfg. map +texnansi-yandy-lucida.map The following file now compiles. However, feelings are bittersweet. I've got something working, but I have no idea why. Nor am I assured that I've found the proper solution. More difficulties could loom on the horizon. Have I done this the correct way? \setupoutput[pdf] \usetypescript[berry][texnansi] \usetypescript[lbr] \setupbodyfont[lbr] \starttext Hello.
