Check the User Guide for Properties files:

Special Characters and Escaping:

If you need a special character in a property like a line feed, a tabulation or an unicode character, you can specify it with the same escaped notation used for Java Strings. The list separator ("," by default), can also be escaped:

key = This \n string \t contains \, escaped \\ characters \u0020

Backslashes are more difficult.

Lists and arrays:

You can specify a list of values in your properties file by using the same key on several lines:

# chart colors
colors.pie = #FF0000;
colors.pie = #00FF00;
colors.pie = #0000FF;
