I like the \u{X} form (where X may be 1-6 hex digits) that seems to be under consideration for ECMAScript. I believe Ruby does this too. But I feel that Turtle should not add anything new here unless it gets into SPARQL too. I feel that the \uxxxx and \UXXXXXXXX forms cannot be removed at this point due to existing implementations and deployed data. Both forms have been in N-Triples since 2004. N-Triples is defined in a W3C Recommendation [1], and Turtle is designed as a superset of N-Triples.
