Why this is a problem is because i need ANSI Colors to work and they can't work of the input isn't one backslash \;

if you use the unicode escape version of \, you can see it is still one single backslash after all
console.log({ content: command });
console.log(command === "\u005C");

{ content: "\\" }
true

I needed to do that for the title to work

nothing wrong here, it's still one single backslash

@joulev that is just the backslash being escaped when console.log'd. same for " for example, it becomes \\" when console.log'd

I tried sending it thru a function in anser which was ansi to json and it still said the content was \ and wouldn't decode.

well yes, because as expected when you type one backslash you get one backslash
essentially, react is working fine here and the command contains exactly what you would expect it to have. how you use that command and whether the library taking that command does perform escaping/sanitisation is not related to react
