 thanks for this, it compiles fine on OS X 10.3 (see below), but segfaults when I run the ruby test with

dyld: ruby Undefined symbols:
___gxx_personality_v0
Trace/BPT trap

Let's take it off-list unless this rings any bells for anyone

Though the answer 'it's not broken' is true in  that Ruby won't mess with your low-level UTF-8/16 bytes, the absence of support for semantics of glyphs is a big hindrance for writing multilingual text handling apps. It's things like having character classes like [:alpha:] and methods like String#upcase that actually work. Looks like ICU4r could address this.
