UTF-8 character encoding problems with ISO-8859-1 encoded Java property files

Java property files need to be ISO-8859-1 encoded. But when it comes to i18n of an application you'll have to overcome the limitations of this character set. In short: ISO-8859-1 does not support all required characters. Changing the encoding of property files to utf-8 is not (yet) supported by Java. To overcome this limitation the guys from http://propedit.sourceforge.jp built an editor named PropertiesEditor. It writes the property file with properly escaped UTF8 symbols.
