Emojis need proper scaping

Only example (this was injected with the emoji feature that pops up when writing in summit. I know that doubling the backslash fixes it by escaping the backslash itself): ¯_(ツ)_/¯

I can search the code and make a PR with the change, I feel bad asking to fix such a small thing. I can also open an issue later today if it's preferred but I can't right now sorry.
