Welcome to TeX - LaTeX Stack Exchange

TeX - LaTeX is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems, people who love to create well-structured and beautifully typeset documents. It's built and run by you as part of the Stack Exchange network of Q&A sites.

With your help, we're working together to build a library of detailed answers to every question related to TeX.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Type 3 fonts can be given encoding vectors as of the pdftex in the 2018 release, thanks to Pali Rohar.

The fix for this would be for Latin Modern to be updated to match the preferred shapes, and to use it in an up-to-date TeX variant such as xe(la)tex or lua(la)tex.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Formats like LaTeX, ConTeXt and plain TeX
  • Engines like pdfTeX, LuaTeX and XeTeX
  • Distributions like TeX Live, MiKTeX, and MacTeX
  • Related software and tools, BibTeX, MakeIndex, LyX, etc.

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to TeX, LaTeX or related typesetting systems
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

Will, Latin Modern is simply not a replacement for Computer Modern. We extensively looked into the idea of using LM pfbs (to get the improvements) with CM tfms, but there are just a few discrepancies in the metrics, mostly relating to accent positioning. But any discrepancies at all are too many, and Jacko did not want to change LM. (Even less so at this late date, I'm sure.) So bluesky pfbs remain the only usable set. <paragraph no idea how to do that> as for xetex and luatex, they are nothing like drop-in replacements for pdftex, let alone knuthian tex, so they aren't the answer here either. - Karl Berry May 26 at 22:45
