Hello. I am trying to enter the following Regex into RegExr in an effort to debug a potential problem with it that has caused a lexer to pick up a trailing parentheses after the closing quotation mark (said parentheses being the end delimiter of function arguments).
The regex I am trying to debug is as follows: /"([\u{0}-\u{10FFFF}]|(\\"))*"/gu (although, it is written in my code as a raw string literal r#""([\u{0}-\u{10FFFE}\u{10FFFF}]|(\\"))*""# - a bug in the lexer library I'm using causes \u{0}-\u{10FFFF} to match any byte, hence the slight weirdness there)
However, attempting to type in the \u{10FFFF} escape results in RegExr failing to identify the escape sequence - it gets marked as invalid. I am using the JavaScript (Browser) regex engine for this, because Unicode. This appears to be a bug, as the sidebar reference indicates that any number of hexadecimal digits may be used within the brackets. Using lowercase F's does not work either.
