Fix isAllowed of escapeStreamer (#22814)
The use of `sort.Search` is wrong: The slice should be sorted, and
`return >= 0` doen't mean it exists, see the
[manual](https://pkg.go.dev/sort#Search).

Could be fixed like this if we really need it:

```

But I don't think so, a map is better to do it.

Switch Unicode Escaping to a VSCode-like system (#19990)
This PR rewrites the invisible unicode detection algorithm to more
closely match that of the Monaco editor on the system. It provides a
technique for detecting ambiguous characters and relaxes the detection
of combining marks.

Control characters are in addition detected as invisible in this
implementation whereas they are not on monaco but this is related to
font issues.

Close #19913
