A DESCRIPTION OF THE REQUEST :
Currently when constructing a java.io.PrintWriter, the charset can only be specified by String. This means two things:
1) I have to catch, or deal with, UnsupportedEncodingException being thrown, and
2) I cannot use the java.nio.charset.StandardCharsets constants to specify the character set that I want to use.

Of course there should be two new constructors:
java.io.PrintWriter.PrintWriter(File, Charset)
java.io.PrintWriter.PrintWriter(String, Charset)

JUSTIFICATION :
Given that I suspect a large portion of the users of this class will just want to write UTF-8, then adding these constructor overloads would make the code simpler. So, instead of:

try {
  new PrintWriter(file, "UTF-8");
} catch (UnsupportedEncodingException e) {
  // Ignore, this is required to be supported by the JVM.
}

we could write:

new PrintWriter(file, StandardCharsets.UTF_8);

Which gets rid of the boilerplate code to deal with the exception that can never happen.

The effort to implement should be relatively minimal, as the internal constructor already expects a Charset.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
That these constructors are added.
ACTUAL -
These constructors have not yet been added.
