[basex-talk] Access to the Unicode Character Database from XQuery?

Hello! I am currently exploring what to do when a footnote callout, which will wind up in an xs:ID value, is something like U+2020 DAGGER; one obvious way is to use the character name. (So instead of an @id value of `Fn1` I'd have `Fndagger` or similar.) I see that the current draft of XPath 4.0 has new-since-3.0 `characters()` and `grapheme()` functions, but so far as I may tell it does not have a way to get UCD properties for a codepoint. Is there an XQuery (or BaseX) way to do this? Thanks! Graydon
