As XeTeX requires dvipdfmx package to correctly render output pdf with unicode Latin Modern fontset, I think it would be wise to add app-text/dvipdfmx to XeTeX dependencies to ensure correct operation by default Reproducible: Always Steps to Reproduce: 1.Render any xelatex document without app-text/dvipdfmx installed 2. 3. Actual Results: No math symbols in math Expected Results: There should be math symbols in equations The similar problem was in Debian distribution. Having app-text/dvipdfmx installed resolved the issue.
it was in app-text/texlive + use xetex, but indeed it makes more sense to have it from texlive-xetex ebuild. Fixed, thanks.
