The Character Model [3] in requirement C045 requires that escape sequences be related to Unicode code point values, not to the code unit values used in some specific Unicode encoding (such as UTF-16). It is a barrier to content authors to have to convert escapes into UTF-16 surrogate pair sequences: it obfuscates the stylesheet, introduces additional processing complexity, and adds no value to support this syntax. Instead, user-agents should be encouraged to better meet the specification. This seems to be the consensus of the CSSWG too, so no worries. ~TJ
