The property file editor in Netbeans 6.0M10 converts unicode escape sequences (e.g \u1234) to the corresponding 
characters when loading a file and - if the character in question can't be saved in the files encoding - back to 
escape sequences on save. This is fine in most cases, but in case of the 'space' character (\u0020) this can lead to 
undesired behaviour, because Java treats escaped and unescaped spaces differently when they appear at the start or end 
of a property value: Unencoded leading and trailing spaces are stripped, but leading or trailing spaces explicitly 
encoded as '\u0020' in the properties file become part of the property value. 

This means that editing a property file may unintentionally change the actual content of the property values because 
the property editor converts explicitly coded leading and trailing spaces to unescaped spaces on save.
