Thinking about it a bit more, I think it would be kinda nice > to have a literal syntax for all Unicode characters. We have categories, so you can use \cX where X is a single letter which denotes a category. Se "M-x describe-categories". This is similar to ?\s, but the available categories are rather ad-hoc. > Something like... er... ?\ucLEFT-TO-RIGHT-OVERRIDE and > \?ucPILE-OF-POO?
