Created attachment 49487
  --> https://bugs.winehq.org/attachment.cgi?id=49487
test files (has Chinese characters in the path name)

this bug was found in a finanical securities software.
program downloaded some html/css/img contents from the internet, and show these
contents in a pop window with builtin mshtml. But actually the pop window's
mshtml just load the html file (like index.html), the img/css/js resources were
not loaded.
I tested builtin iexplore and found the same problem.
finally I found there are some Chinese characters in the path. if I remove them
or change them to English characters, It will be all fine.

Please see the test files in attached test.tar.gz. After uncompress it, use
native ie to open index.html, for example:
wine iexplore "file:///c:/测试用/index.html"

if css/js load success, the background color of the window will be black, text
will be white, and you will see "you should see me!" which writen by js. if
failed, you will just see black "Hello World" in a white background.
