java.util.Properties encoding

I get different results on two different systems and don't know why.

Properties prop = new Properties();
prop.load(new ByteArrayInputStream(input)); //input is byte[]

On both systems input contains "var=\\u00C4\\u00DC\\u00D6\\u00E4\\u00FC\\u00F6".

On my test system prop contains "var=ÄÜÖäüö". (This is what I want)

On another system prop contains "var=\xC4\xDC\xD6\xE4\xFC\xF6". This is input in hex, but why does Properties do this? I unfortunately know nothing about the other systems configuration.

Has someone an idea about the reason?

Java .properties files are encoded with ISO-8859-1 (Latin-1), NOT UTF-8. All non-Latin-1 characters must be entered by using Unicode escape characters, e.g. \uHHHH.

An alternative is to use the XML format for properties, which IS UTF-8.
