<i18n dev> native2ascii be removed from JDK?

[Mandy Chung]

There are several existing ways to do native to ascii conversion.  For 
example, IDEs like NetBeans and IntelliJ support the transparent 
native-to-ascii conversion. There is also maven native 2 ascii plugin.

JEP 226 proposes to support UTF Properties file that will address the 
original motivation of creating the native2ascii tool.

While native2ascii used to be a convenient tool for some developers to 
use, it may be time to remove it in JDK 9 and developers can use IDEs 
and Maven plugin and other build tools.

Any thought?
