Hi,
Was on vacation, I started to prepare the patch from webrev.04
for integration. Please note: made some adjustments to your
patch to pass jcheck, ie. usage of tabs and space at line endings,
and modifications to Copyright dates.
Also fixed a minor bug on unix replaced JLI_TRUE with JNI_TRUE.
I have attached a patch to for your reference.
However, there is a regression test failure on Windows,
jdk/test/tools/launcher/I18NTest.java
---Test info----
Executed command: C:\mmm\jdk\bin\javac.exe i18nH▒lloWorld.java
++++Test Output++++
javac: file not found: i18nHélloWorld.java
----End test info-----
Have you run all the launcher regression tests with this changeset ?
Thanks
Kumar
Hi Kumar, just wondering if there are any updates on processing this submission.
Thanks!

Hi Martin, et. al.,
Sorry for not getting back earlier, I am very busy right now with my other
large commitments for JDK9.
I will sponsor this "enhancement/bug fix" sometime in the new year, meanwhile,
there is the changeset [1] which is likely to cause merge conflicts, and perhaps logic
issues.
Thanks
Kumar

Hi Kirk,
Thanks for proposing this change.
If you notice all the posix calls are wrapped in JLI_* this gives us the ability to use
"W" functions. I almost got it done, several years ago, but we upgraded to VS2010 and my
work based on VS2003 keeled over, meanwhile my focus was "shifted" to something else.
main.c: is really envisioned to be a stub compiled by the tool
launchers, like java, javac, javah, jar etc. I prefer to see all the
heavy logic in this file moved to the platform specific file
windows/java_md.*
For the reason specified above we need to move fprintf or any naked posix calls
to JLI_* indirections.
I don't see any tests ? The tests must be written in java and placed in
jdk/test/tools/launcher, there is a helper framework TestHelper.java.
There are other changes in nio, charsets etc, this will be reviewed by my
colleague specializing in that area (Sherman) cc'ed.
Thanks
Kumar

This webrev intends to address interaction between Windows console and java
apps.
Two switches were added that change the behavior of the launcher. The defaults
do not change the launcher behavior.
-Dwindows.UnicodeConsole=true - switches on Unicode support in the Windows
console. This optional switch causes the launcher to call GetCommandLineW() and
parse the arguments in unicode. It also modifies how the codepage for console
output is selected.
-Dfile.encoding.unicode="UTF-8" - identifies Unicode charset to use; If
not specified, UTF-8 is used by default. Ignored when windows.UnicodeConsole is not set
to true. When the first switch is used, this optional switch allows the codepage for
console output to be controlled.
I would like to get feedback on the approach here and any additional work that
is required solve these particular Unicode issues on Windows.
