--------------------------------------------
The patch for CONFIGURATION-715 covers this issue as well.
> PropertiesConfiguration: Escape sequence handling different from Properties
> ---------------------------------------------------------------------------
>
> Key: CONFIGURATION-716
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-716
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 2.3
> Reporter: Patrick Schmidt
> Priority: Major
>
> The escape sequence handling in PropertiesConfiguration is different from
> java.util.Properties.
> The Javadoc (of java.util.Properties) basically states that if an escape
> sequence (backslash + character) is not understood, the backslash is simply
> removed. PropertiesConfiguration keeps the backslash. E.g. "\ " (backslash +
> space) should result in just a space. This sequence is used by Properties to
> escape the first leading space in a property value when writing to a
> properties-file. PropertiesConfiguration does not understand this syntax.
> Also (which is technically a different issue but pretty close to this one)
> does not preserve leading spaces in property values when saving. One could
> use \u0020 to encode the first leading space, but it would be nicer if it
> could just use the simpler "\ ".
