Great! Go ahead!

All of these methods are coming with Supplementary Character Support of

Where does the data come from?

2.Delegate these methods to ICU4J, which provides extensions to the

I prefer this option, although ICU doesn't reponse very quickly. If icu4j
works well, I think there's no reason for Harmony to reinvent the wheel.

If there are some series bugs in ICU4J which may affect our goal, it's
another story.

For now, I strongly recommened you to study icu4j and take a try!  Good
luck. :-)

What's your opinion? Any suggestion are welcome :)
