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

[KIRIYAMA Takuya]

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).
