RFR: 8293579: tools/jpackage/share/jdk/jpackage/tests/UnicodeArgsTest.java fails on Japanese Windows platform [v2]

> Could you please review the JDK-8293579 bug fixes?
> 
> tools/jpackage/share/jdk/jpackage/tests/UnicodeArgsTest.java attempts to give 
> the launcher the character which is encoded by Windows API WideCharToMultiByte() 
> from UNICODE "é"(0x00e9) as an argument. However, this test fails because the 
> code point "é"(0x00e9) cannot be treated on Japanese Windows.

> WideCharToMultiByte() encodes characters as Shift-JIS on Japanese Windows, but 
> the code point "é"(0x00e9) does not exist in Shift-JIS, and it is replaced with 
> "e"(0x0065) as substitute. Therefore, "é"(0x00e9) and "e"(0x0065) are compared 
> in this test and judged to be different characters, and return as failed.
> 
> So, in the Japanese encoding("MS932", "SJIS"), the test should be modified to 
> give a character such as "あ"(0x3042) as the launcher's argument instead of 
> "é"(0x00e9).
