using Unitful: °C

In a jmd file at path path, then run:

weave(path, doctype="md2pdf")

You can solve such problems by manually adding dependencies in the YAML header. An example is:

---
title:    .jmd YAML header injecting TeX dependency
tex_deps: \usepackage{gensymb}
          \usepackage[nameinlink]{cleveref}
weave_options:
   doctype:    md2pdf
---

In your case gensymb is the one you need.

Unfortunately, this solution doesn't work for me because of #418.
