Any suggestion are welcome :) This task is to update current implementation of java.lang.Character, about some new feature of J2SE 5.0, it's important to reduce the risk of changing such a core class. The "HashMap" method may introduce more complexity and more maintenance effort into Harmony development, so I think delegating to ICU4J is the better choice. The only concern is that: does the ICU4J we currently using meet our need perfectly?
IMHO, the icu4j_3.4.4 which supports Unicode 4.1 will meet our requirement. Best regards, Richard
