Highlight illegal characters #2960
Description
Description
The syntax highlighting that vimtex provides doesn't seem to highlight illegal characters, e.g. an underscore in the document body.
Steps to reproduce
minimal.vim
set runtimepath^=~/.vim
let &packpath = &runtimepath
call plug#begin()
Plug 'lervag/vimtex'
call plug#end()minimal.tex
\documentclass{article}
\begin{document}
Illegal characters should be highlighted: _
\end{document}Expected behavior
If I run nvim -u none minimal.tex (i.e. default colorscheme, not loading vimtex), then the illegal underscore is highlighted red.
Actual behavior
If I run nvim -u minimal.vim minimal.tex, the illegal underscore appears normal.
Do you use a latexmkrc file?
