Hello!
I have a bookdown book some greek symbols inline. I tried to add them as unicode, and also in the visual RStudio (insert>special characters). It looks like this
TNF- ⍺
Looks fine in word and HTML, but not in PDF. If I do the standard pdfLaTeX there is a unicode error, if I change to
output file: dell.knit.md
! LaTeX Error: Unicode character α (U+03B1)
not set up for use with LaTeX.
Error: LaTeX failed to compile dell.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See dell.log for more info.
Execution halted
I has had a similar problem recently and I could not resolve it with Rstudio (I posted an issue for kind of unrelated package Writing equations in the response · Issue #1 · pjbouchet/respondR · GitHub). What I did at the end, I editted the resulting docx file and insert greek symbols and some math formulas manually
