Re: [csswg-drafts] [css-syntax] The tokenizer input should probably be a stream of scalar values, not codepoints (#3307) from Simon Sapin via GitHub on 2018-12-20 (public-css-archive@w3.org from December 2018)

What one case do you mean and how is it allowed? If "the input stream" (before substitution/processing) is defined as scalar values rather than code points, the surrogate case just does not exist in css-syntax. Then it up to users of that entry point (rather than the bytes based one) to provide scalar values. In DOM/CSSOM, this happens to be USVString. (I guess we’d need some more prose in HTML for `<style>` and in css-style-attr.)
