 |Character  | Why escape it?
 |-----------|--------------|
 | `0-9`     | So that in `new RegExp("(foo)\\1" + RegExp.escape(1))` the back reference will still treat the first group and not the 11th and the `1` will be taken literally - see [this issue](https://github.com/benjamingr/RegExp.escape/issues/17) for more details.   | 
-| `0-9a-fA-F` | So that `new RegExp("\\u41" + RegExp.escape("B"))` will not match the letter "Л" (`\u041B`) but rather the sequence "AB", or more generally that a leading hexadecimal character may not continue a preceding escape sequence - see [this issue](https://github.com/benjamingr/RegExp.escape/issues/29) for more details.   | 
+| `0-9a-fA-F` | So that `new RegExp("\\u004" + RegExp.escape("A"), "u")` will not match the letter "J" (`\u004A`) but rather throw a type error (or that without the `u` flag, the sequence "u004A" would be matched, `\u` being an identity escape), or more generally that a leading hexadecimal character may not extend a preceding escape sequence - see [this issue](https://github.com/benjamingr/RegExp.escape/issues/29) for more details.   | 
 
 Note that if we ever introduce named capturing groups to a subclass of the default `RegExp` those would also need to escape those characters.
