 ## Not-Yet-Supported syntax
 
 I plan to add the following features to the gem, but have not yet got round to it:
 
 * Throw exceptions if illegal syntax (see below) is used. This is currently only partially implemented (for lookarounds only).
 * POSIX bracket expressions, e.g. `/[[:alnum:]]/`, `/[[:space:]]/`
 * Options, e.g. `/pattern/i`, `/foo.*bar/m`
-* Escape sequences, e.g. `/\xa1/`
-* Unicode characters, e.g. `/\u06E9/`
 * Named properties, e.g. `/\p{L}/` ("Letter"), `/\p{Arabic}/` ("Arabic character"), `/\p{^Ll}/` ("Not a lowercase letter")
 * Subexpression calls, e.g. `/(?<name> ... \g<name>* )/` (Note: These could get _really_ ugly to implement, and may even be impossible, so I highly doubt it's worth the effort!)
