Hi Naoto,

Do we need a test similar to ISO3166 where display names of Locale.ROOT and Locale.US are compared? I see LocaleEnhanceTest.java has references to Locale.ROOT and a few selected names were updated. But we don't seem to have a test like ISO3166 that does a straight-forward comparison.

The code you used to generate the updated LocaleNames.properties (in the comment section), that seems to be valuable. I wonder if there's a better way to preserve it, as part of the manual tool, or maybe put it back into the repo as part of a test?
