"Higher" here means "larger codepoint". > Thanks for the clarification regarding these particular hexadecimal codepoints. Based on your feedback, my conclusion is that 4.1.3 is in this respect is unclear. The current spec states "... [identifiers] can contain only the characters [a-z0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, or a hyphen followed by a digit. Identifiers can also contain escaped characters and any ISO 10646 character as a numeric code ..." If indeed the Number Sign is lower than U+00A1 then how can it be acceptable within in an identifier, without being escaped?
