I don’t use vimtex, but this looks to be related to the encoding of international characters. In the vimtex getting started, I found this in the requirements:
UTF8 character encoding enabled (enabled by default in Neovim; place the line set encoding=utf-8in your vimrc).
See :help vimtex-requirements for details on requirements for using VimTeX.
