Class CharsetMapper

org.apache.catalina.util.CharsetMapper
Utility class that attempts to map from a Locale to the corresponding character set to be used for interpreting input
text (or generating output text) when the Content-Type header does not include one. You can customize the behavior of
this class by modifying the mapping data it loads, or by subclassing it (to change the algorithm) and then using your
own version for a particular web application.
