Hi all,

Please review this change:

   JBS: https://bugs.openjdk.java.net/browse/JDK-8249215
   webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8249215/webrev.00/

I tried to run Sample.java in JDK-8236161 with -Dfile.encoding=UTF-8, but JVM crashed due to internal error on fastdebug VM. I saw same call stack with JDK-8236161 in hs_err log.

I investigated it, then I found out current implementation cannot handle default charset.

If charset is set to UTF-8, it would be handled as "DEFAULT_CHARSET" in WFontConfiguration::initTables. However it does not affect native font name, so we cannot find valid font.

This change has passed all tests on submit repo (mach5-one-ysuenaga-JDK-8249215-20200711-0655-12566039)
