Eclipse Android Unicode Folder Names causing bad build

In my Android project, I put several folders with unicode names in the assets folder开发者_如何学JAVA. Eg "Ελληνικά" and "中文（繁體）"

When I do so, I can not built the app. I get this error. However, when I rename the folders to simple ASCII it works.

[2010-07-21 21:12:58 - Ridvan Library] ------------------------------
[2010-07-21 21:12:58 - Ridvan Library] Android Launch!
[2010-07-21 21:12:58 - Ridvan Library] adb is running normally.
[2010-07-21 21:12:58 - Ridvan Library] Could not find Ridvan Library.apk!

It appears Android does not yet fully support all Unicode in code and folders.
