Finally a good reason to run Rails on Java! :-)
- We've been kicking around the possibility of migrating to a mutable UTF-8 string inside JRuby, to avoid the wasted high byte and to get all our mutability in a single type that's friendlier than what Java provides. If we could say that the base JRuby String implementation supports a fast, solid UTF-8 backing store normally and MultiByte's String#chars and Chars for actual multibyte operations I think we'd have the best of all worlds
Sounds like the way to go to me. UTF-8 is what Ruby has (although limited) built-in support for and for most Rails apps it's what you have to convert to in the end anyway.
Please not that ActiveSupport::Multibyte support all Unicode planes and not only the Basic Multilingual Plane. My knowledge of Java is very limited, but judging from the article at [1] working with anything beyond U+FFFF takes some serious effort.
