I am trying to understand how fonts work with (plain) LuaTeX.
I use the standard ConTeXt suite, and I made a luatex-plain format using the file luatex-plain.tex from the distribution:
luatex --ini luatex-plain.tex
If I define this file (foo.tex)
\font\test=cmbx10 \test NZQRC \bye
It compiles okay with
luatex --fmt=luatex-plain.fmt foo.tex
The same also works with TrueType fonts.
But if I use the msbm10 font ("blackboard"), I get:
!LuaTeX error (file msbm10): Font msbm10 at 72 not found ==> Fatal error occurred, no output PDF file produced!
If I add the
\starttext ... \stoptext and compile it using
context instead of
luatex, it works all right.
So, at this point I am quite puzzled. How can I use the msbm10 font in plain LuaTeX?
Edit: The problem was that I was using luatex from a ConTeXt installation. With luatex from TeXlive, it works all right. Thanks.
