-## Embedding fonts in PDFs
-
-To check whether fonts are embedded, use `pdffonts`, which is included with `xpdf`. `pdffonts` gives output that looks like this:
-
-```text
-$ pdffonts paper.pdf
-name                                 type         emb sub uni object ID
------------------------------------- ------------ --- --- --- ---------
-FHQIOS+NimbusRomNo9L-Medi            Type 1       yes yes no       6  0
-NEESMN+NimbusRomNo9L-Regu            Type 1       yes yes no       9  0
-PJQNOS+CMSY10                        Type 1       yes yes no      12  0
-```
-
-You want `emb` to be `yes` for all fonts (and possibly `sub` as well; also, all fonts should be Type 1, not Type 3). By default in Ubuntu, pdflatex should embed all fonts. Just in case, you can check `/etc/texmf/updmap.d/00updmap.cfg`, which should have a line like this:
-
-`pdftexDownloadBase14 true`
-
-If it's set to `false`, change it to `true`, then run `update-updmap` as root. Remake the PDF; if it still has non-embedded fonts, your figures are probably to blame. Check your PDF figures and make sure their fonts are embedded (using the `pdffonts` command). For anything that doesn't have embedded fonts, you can try the following magical invocation:
-
-```
-gs -dSAFER -dNOPLATFONTS -dNOPAUSE -dBATCH -sDEVICE=pdfwrite \
--sPAPERSIZE=letter -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer \
--dCompatibilityLevel=1.4 -dMaxSubsetPct=100 -dSubsetFonts=true \
--dEmbedAllFonts=true -sOutputFile=figures/Mprime-new.pdf -f figures/Mprime.pdf
-```
-
-This creates a file `figures/Mprime-new.pdf` that is hopefully identical to the input file `figures/Mprime.pdf`, except that the fonts are embedded. Run `pdffonts` on it to check.
-
-Once all your figures are in PDF format, remake the paper again. Hopefully, all your fonts are now embedded --- check again with `pdffonts`.
