Hold Java style properties as key-value pairs and allow them to be loaded from or saved to a ".properties" file. The file is stored with character set ISO-8859-1 which extends US-ASCII (the characters 0-127 are the same) and forms the first part of the Unicode character set. Within the application string are Unicode - but all values outside the basic US-ASCII set are escaped.
