Maybe UnicodeEscaper.outsideOf(00, 0xff)?

>                 Key: CONFIGURATION-538
>                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-538
>             Project: Commons Configuration
>          Issue Type: Bug
>    Affects Versions: 1.9
>         Environment: shouldn't be important, but 64bit Windows 7
>            Reporter: Ats
>            Priority: Major
>              Labels: PropertiesConfiguration,, charset, encoding,, save
>
> I created JUnit test http://goo.gl/GCwi2, that uses two methods to save PropertiesConfiguration (with property value containing utf-8 characters) into file:
> 1) propsConf.save(file); // propsConf.setEncoding("UTF-8") was called before
> and
> 2) propsConf.save(fileOutputStream, "UTF-8");
> Test shows that file doesn't contain UTF-8 characters. Instead saved file contains unicode escapes of non ISO-8859-1 characters.
> This seems wrong, as documentation on setEncoding() method says:
> "Set the encoding used to store the configuration file".
> PropertiesConfiguration.setEncoding() method currently seems to affect only loading the configuration.
> I added one test method that shows that even java.util.Properties class saves the same property value without any problems using utf-8 characters (not unicode escapes that it ) when using smth like that:
> props.store(new OutputStreamWriter(fos, "UTF-8"));
> It looks like a bug to me, or did i misunderstood smth?
