Unable to start jboss AS on windows if installed on path containig non-ascii characters

1.) Install jboss into a folder containing non-ascii characters. (i.e. "C:\Testチ").
2.) run standalone.bat

C:\Test?\jboss-as-7.1.1.Final\bin>set JAVA_HOME=C:\Program Files\Java\jre7

C:\Test?\jboss-as-7.1.1.Final\bin>standalone.bat

3.) pleas note that: "Testチ" used in path -> 'チ' does not bellong to system locale code page. E.g.: char 'チ' is in CP 932, system locale code page used 437/1252,..

4.) i would also like to add that jboss does not start if it installed in "normal" folder, but JBOSS_CONFIG_DIR && JBOSS_LOG_DIR are set to folder with non-ascii characters:

c:\test\jboss-as-7.1.1.Final\bin>set JBOSS_LOG_DIR=c:\Test?

c:\test\jboss-as-7.1.1.Final\bin>set JBOSS_CONFIG_DIR=c:\Test?\configuration

c:\test\jboss-as-7.1.1.Final\bin>dir %JBOSS_CONFIG_DIR%
Volume in drive C has no label.
Volume Serial Number is 2C2F-FA6F
