Hi,

I'm not sure how to approach this: suppose I want to produce html output from a .bib file uses LaTeX commands such as `\textregistered`, or `\myname` as an alias, etc. but outside a math environment (`$\textregistered$` would be fine, as it's handled as Inline Math and passed to mathjax). 

With a different input format, I could use the `+raw_tex` extension to make sure pandoc does not drop the latex commands, and have a Lua filter perform the desired substitutions, as in this answer: https://stackoverflow.com/a/56391373

Unfortunately, I'm getting this message from pandoc: "The extension raw_tex is not supported for bibtex"

Is there a workaround for such substitutions?

Many thanks,

baptiste
