Customizable PDF fonts

[delameter]

Hello again.

After making several PDFs noticed that there is no embedded fonts inside. That was expected, but default document viewer renders them in Times font (Times New Roman), also known as "Font of Pain" in my homeland. (because de facto it's a standard font for papers and essays in universities).

Next I tried to substitute it with something better using Ubuntu system font manager, but these rules are simply ignored, maybe because the fonts are already substituted, I have no idea.

The question is, how hard would it be to add an option/configuration value to set font family for produced PDFs? With or without embedding. I ran through groff man page but didn't see anything similar. What I did found is that groff can make TeX files, so theoretically it's possible to make a "tex" file, add directives to setup fonts, and feed it to latex to grab a PDF, but I hope there is a more elegant way to do it.

Thanks
