When trying to print document, at one point, all characters become "weird"

## Scope

- I have a fairly large document on hackmd
- I want to store the document as a pdf often, but I cannot as hackmd doesn't allow me. Using a markdown to pdf converter is not an option, as my document contains hackmd specific syntax (e.g. sequence diagram)
- In essence, I want to send via PDF, because a colleague of mine doesn't have hackmd. And he doesn't want to sign up. So for me it's easier to just send a PDF.
- So what I do is I go in the "view" mode and I press CTRL + P to print to PDF
- But then I get what is in this screenshot below (both with Chrome and Brave)
