A DESCRIPTION OF THE REQUEST :
UnsupportedEncodingException has a

 toString(String charsetName)

method but no

 toString(Charset)

method.

JUSTIFICATION :
Every class that provides a conversion from bytes to string should have a method that takes a Charset object as a parameter.

Otherwise conversion between Charset and charset name has unnecessarily to be done, and UnsupportedEncodingException have to be handled where they could not occur.

ACTUAL -
The implementation is missing.

CUSTOMER SUBMITTED WORKAROUND :
See above.
