I'm now trying Beta ml installer on Windows and Solaris,
It seems that all localized component names are garbled,
unicode ascii (¥uXXXX) are being displayed as they are.
Other UIs are OK.
If you don't have Japanese environment, try --locale ja option.
I haven't much updated installer messages so I think
the problem exists in installer side.
Please let me know your evaluation and possibility
for bugfix at Beta.
If we can not fix it quickly (for Beta), I'll try to
revert all components names to English as workaround.
Workaround is implemented by Masaki for Beta.
The fix is going to be done by FCS.
The issue is actually the regression after my fix in main #128dc7ed964d, in particular  and .
Actually that commit allows to build RCP Installers when the application title (app.title in nbproject/project.properties) and the path to the project contain Unicode chars.
But it also raised this issue: after looking into it it seems that LoadLocales  ant task handles properties loaded from <basename>.properties and <basename>_<locale>.properties in a different way: in partucular, it additionally convert property value to ascii if the property is loaded from <basename>_<locale>.properties. And that is apparently wrong (should be handled the same way for default, and for locale-specific .properties file).
fixed in core-main#0e3ed2cceec8
