Perhaps Unicode could just have tables listing all relevant sequences of symbols, instead. So "latin letters lowercase" would list the codepoints for a-z in ord

Perhaps Unicode could just have tables listing all relevant sequences of symbols, instead. So "latin letters lowercase" would list the codepoints for a-z in order, for example. Would no longer matter if the codepoints themselves are sequential or not. (And relevant to my country, "Swedish characters lowercase" would map to latin letters lowercase + åäö.)

Characters have a script associated with them (e.g. Latin), and caseness is also part of a character's properties. Now, language-specific subsets¹ of those are a bit iffy to deal with.
