But now the "defaultEncoding" is always UTF-8, the setup code appends the non-ASCII suffix, which fails to read in the native code using iconv with US-ASCII. The setup code should use the encoding from "sun.jnu.encoding" instead. Actually, the code there was copied from UnicodeTest.java which was modified with JDK-8260265, so the same fix needs to be applied.

Doesn't it depend on the OS version and which file system is being used? HFS+ seems to use UTF-16
