Today, After reading the chapters about typography and fonts in the reference manual, I tried to define my own typescript. After mtxrun --script fonts --reload, I wrote the codes like this:
% century.ttf in C:\Windows\Fonts
\starttypescript[serif][centuryfont][name]
\definefontsynonym[Serif][century]
\stoptypescript
\definetypeface[newfont][rm][serif][centuryfont][default]
\setupbodyfont[newfont,12pt]
\starttext
...
\stoptext
It is so small, but only to test my usderstanding. When it succeeded, I changed the century in the third line to palatinolinotyperoman which could be searched by mtxrun --script fonts --list --all --pattern=pala*. Sadly, this font(pala.ttf) cannot be loaded.
I don't know why :-(
