Please provide the means of allowing to highlight words enclosed in backticks `

Hello,
I noticed there is no definition option to make the editor highlight words between backticks `
However, there are other, rarely found in my view and obscure symbols. I frankly would not call them brackets.
It’d be even better if we could custom define what gets highlighted between what characters.
Please see the screenshot of what I am referring to:


I need this for certain languages as MySQL SQL dialect.
