Looks like there's some sort of GBK vs UTF-8 mixup going on, because
'=E9=8F=82=E7=89=88=E7=85=A1=E9=8F=82=E5=9B=A9=E5=B0=9E' is the same byte s=
equence in GBK as '=E6=96=B0=E6=9F=A5=E6=96=87=E7=8C=AE' is in UTF-8:
\xE6\x96\xB0\xE6\x9F\xA5\xE6\x96\x87\xE7\x8C\xAE

I take it the actual directory name is '=E6=96=B0=E6=9F=A5=E6=96=87=E7=8C=
=AE'? (Babelfish seems to be
able to make some sense of that one but not the other.)

Do you know what the encoding of your batch file is? And have you got
any locale variables (LC_ALL, LC_CTYPE, LANG) set when invoking it?

Hmm, perhaps the argument mangling at program startup is using the
ANSI codepage (i.e. GBK in this case) when it should be using UTF-8?
