Re: bslib and rmarkdown update

[Eric Brown <eb@ericebrown.com>]

Hi again,

I tried to see what happens when the woff files are deleted from bslib.

I cloned the bslib git, deleted the contents of the font folder, built
the R package locally, then tried to render an R markdown document
that uses a bslib theme (minty).
It fails with an error message (below).

pandoc: /tmp/Rtmp1sYpTM/bslib-ca23be8b2c03436a7d75cedd4667b7ed/fonts/JTUSjIg1_i6t8kCHKm45xW0.woff:
openBinaryFile: does not exist (No such file or directory)
Error : pandoc document conversion failed with error 1
Error: callr subprocess failed: pandoc document conversion failed with error 1
Type .Last.error.trace to see where the error occurred

Best,
Eric
