Conceptually interesting, and I'd love to know how well that'd perform in real-world usage. Would do very nicely on blocks of text that are all from the same range of codepoints, but if you intersperse high and low codepoints it'll be like 2 but with significantly more complicated lookups (imagine a "name=value\nname=value\n" stream where the names and values are all in the same language - you'll have a lot of transitions).
