[jdk21u-dev] RFR: 8353698: Output of Simple Web Server is garbled if the console's encoding is not UTF-8

[Taizo Kurashige]

Hi,

This is a backport of JDK-8353698: Output of Simple Web Server is garbled if the console's encoding is not UTF-8

Original patch applies cleanly to 21u.
This PR depends on #1980. So #1980 shoud be integrated first.

Testing: test/jdk/com/sun/net/httpserver/simpleserver passes on Japanese Windows and English Windows.

Thanks.
