fmt_currency() to pdf output doesn't show € symbol

[ThierryO]

Prework

• Read and agree to the code of conduct and contributing guidelines.
• If there is already a relevant issue, whether open or closed, comment on the existing thread instead of posting a new issue.

Description

Using "EUR" currency displays "EUR" in pdf instead of of the € symbol.

Reproducible example

• Post a minimal reproducible example so the maintainer can troubleshoot the problems you identify. A reproducible example is:
  • Runnable: post enough R code and data so any onlooker can create the error on their own computer.
  • Minimal: reduce runtime wherever possible and remove complicated details that are irrelevant to the issue at hand.
  • Readable: format your code according to the tidyverse style guide.

Thanks for filing this issue. Agree that this is substandard in LaTeX. This will be fixed up alongside the work done for #1346.
