We have an HTML pattern that looks like this:

<input type="text" pattern="[^\x00-\x08\x0B\x0C\x0E-\x1F\x7F-\x9F\uE000-\uF8FF\u{F0000}-\u{FFFFD}]*"/>

Observe the \u{F0000}, this is valid JS syntax but in java it should be \x{F0000}.
Is it possible to add this to the RegExpJsToJavaConverter.convert() method?
