I have a style file I used for a project in pre-Unicode age. Now I want to convert it for use in XeTeX. I used Computer Modern and now would like to use CMU Serif. Pointers on what to do with the following block of code will be much appreciated.

\font\BIG=cmr17         %for titlepages
%\font\mid=cmr12 scaled\magstep1
\font\ninesc=cmcsc9     %for headers
\font\bfxiv=cmbx12 scaled \magstep1

%              \def\itbf{\eightitbf}%

    Welcome to TeX.SX! The most important aspect is whether you're using accents in your text.

  • Yes, my text contains many accents. I believe the version of CMU Serif I am using has been doctored to accommodated most of the diacritics that I need. (I work on Vedic Sanskrit.) Sep 3, 2015 at 13:29
  • If you don't use the “old commands” such as \' or \., but always Unicode characters, there should be no problem

I won't convert every of your commands but three typical can be done like this

\font\BIG="CMU Serif" at 17pt 
\BIG blablb

\font\sc="CMU Serif:+smcp"
\sc Blabla

\font\itbf="CMU Serif/BI"

enter image description here

You can find some information about the various font settings in xetex-reference.pdf

  • Thanks you. This is a great start. I'll try to take it from here. Sep 3, 2015 at 13:30
