Robocopy /UNILOG 参数生成的日志实质是GBK的编码？

523066680

1. robocopy /L /MIR /copyall /TEE "%src%" "%dst%"  /XD %fold% /XF %file% ^
   
2.          /UNILOG:"UniLog%dt:/=-%.txt" /X /FP /NS /NDL /NP
   

复制代码

其中 /UNILOG 参数的作用

     :: 以 UNICODE 方式将状态输出到日志文件(覆盖现有日志)。

实际执行后生成的文件，开头两个字节是UTF-16LE 的BOM \xFF\xFE
但是后面的内容全都是GBK编码的，Are you kidding me?

这里有一个相同问题的帖子（可能要翻*访问）：
http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/windows-7-robocopy-unilog-option-appears/83d01ade-7dc7-4094-9dd0-90369b4bbced

Question

Windows 7 robocopy /UNILOG option appears completely broken

I tried to use /UNILOG:logfile with robocopy and the output file is corrupt.

It has the UNICODE BOM (FFFE), but the characters that follow are ANSI, except for the line of text
following "Options :", which does consist of actual UNICODE characters.  However, immediately following
that, it reverts back to ANSI, and if any of the files/paths in the listing really had a wide character, it is
obliterated (appears as a single '?', so not even UTF-8).

I don't suppose there's any hope to see this fixed, since the story on Windows 8 robocopy is that it
has even more bugs?
