What escape codes are supposed to be supported in ReScript strings?

Both 9.1.2 (playground) and 9.1.4 both support things like "\000\255" which is not supported in JS, but master does not. The documentation of primitive types doesn’t provide much detail about escapes. The introduction page does state the following though:

ReScript looks like JS, acts like JS, and compiles to the highest quality of clean, readable and performant JS, directly runnable in browsers and Node.

This makes me think that "\000\255" should not be supported moving forward. Is it safe to assume that’s why this no longer works on master?

JavaScript supports decimal octal escape codes whereas OCaml uses the same syntax for decimal escape codes.
