I made a tool for Linux (it'll probably work on quite a few flavors of *BSD as well and maybe macOS) that converts gemtext files to pdf using groff, aptly named "gmi2pdf". Can save as "A4", "Letter", "Tabloid", and "Legal" sized PDFs. It can take a local file or a gemtext/plaintext remote gemini resource as input. Has support for TLS client certs as well. Currently only supports ASCII characters, but can optionally convert unicode characters to squares. Some lines can look a bit weird for now due to the justified alignment. Can be cloned via git or https from vigrey.com/git/gmi2pdf. Some repo info can be found at gemini://vigrey.com/git/gmi2pdf

Lovely, looking forward to the UTF-8/Unicode version.

Will you add support for changing the font and size for all the types of text?

Possibly at some point. I mostly needed a tool to archive gemtext files as pdf files so I could print them out at my local public library. I'll need to figure out more about font support with groff as well to add unicode support, although groff does natively support some accented characters. Might add support for text size changing, but we'll see.

I found this in the groff documentation

(Search for unicode)

Cool! Unicode can be difficult. I ended up running my gemtext files through a PHP script to convert to HTML and then into a browser to render the Unicode characters, then using the browser's print-to-pdf capability. The entire process is scriptable. I'll have to give this a try.
