java.lang.Objectfilters.SetCharacterEncodingFilter
Example filter that sets the character encoding to be used in parsing the incoming request, either unconditionally or only if the client did not specify a character encoding. Configuration of this filter is based on the following initialization parameters:
ignore initialization parameter. This parameter
is required, so there is no default.selectEncoding() method is set. If set to "false,
selectEncoding() is called only if the
client has not already specified an encoding. By default, this
parameter is set to "true".Although this filter can be used unchanged, it is also easy to
subclass it and make the selectEncoding() method more
intelligent about what encoding to choose, based on characteristics of
the incoming request (such as the values of the Accept-Language
and User-Agent headers, or a value stashed in the current
user's session.
