1. Create EntApp using ja chars in its name 2. Expand Java EE Modules node I'm running in the Japan locale, using a pseudo localized Netbeans. Java EE Modules looks with underscore signs. In en_US they are ok.
Created attachment 46340 [details] using ja chars in name
Created attachment 46341 [details] in eng looks ok
This situation is caused by replacing some characters in archive names - try to create Web project with this kind of name and then build WAR file... The same applies for Java SE project. So I think that this behaviour is correct because we show archive names not project names.
