RFR: 8285517: System.getenv() returns unexpected value if environment variable has non ASCII character

Sun Apr 24 09:26:41 UTC 2022

On JDK19 with Linux ja_JP.eucjp locale,
System.getenv() returns unexpected value if environment variable has Japanese EUC characters.
It seems this issue happens because of JEP 400.
Arguments for ProcessBuilder have same kind of issue.
