tilde in a string throws error

**Versions**
"cypress": "^9.1.0",
"@cypress/code-coverage": "^3.9.12",

**Describe the bug**
I have a line in my code :
```js
mask += '~`!@#$%^&*()_+-={}[]:";\'<>?,./|\\';
```
this is leading to an error : SyntaxError: Unexpected token x in JSON at position 2509710
from the command
```js
const coverage = JSON.parse(sentCoverage)
```
from `code-coverage/task.js`

when I dive into the sentCoverage it is a string generated by the command `JSON.stringify(appCoverageOnly)`, it looks like this in the problematic section:
```
}\n if (chars.indexOf('!') > -1) {\n mask += '\x7e`!@#$%^&*()_+-={}[]:\";\\'<>?,./|\\\\';\n }\n\n `

```

Basically my tilde is getting converted to \x7e and this cannot be parsed as JSON. Everything works perfectly if I just get rid of that one character

Please let me know if more details are warranted.
