Hi there

In a markdown document I can add for the LaTeX writer the following in the YAML metadata blocK:

---
header-includes:
  - \usepackage{tikzsymbols}
...

Then I can use in the document things like \Cooley[-3][cyan] and more. :-)

However I was not able to add this \usepackage declaration to a defaults file. I tried in my defaults file myarticle.yaml the following:

from: markdown+raw_attribute
metadata:
  documentclass: scrartcl
  header-includes:
    - \usepackage{tikzsymbols}

but then I get the Latex error:

! LaTeX Error: Missing \begin{document}.
[...]
l.46 \textbackslash

Somehow the \usepackage{tikzsymbols} command is now „escaped“ so that the backslash get printed out... How can I avoid this and give the \usepackage declaration in the defaults file?

Thanks for any pointers!
