I found it can not work properly when there are Chinese characters in urls,both 0.9.1 and 0.9.2beta have this problem.

In the path, or in the domain name?

in the path,
such as :

"http://iris.trueice.net:8000/Songs/English/Misc/体育歌曲/The%20Official%20UEFA%20Euro%202004%20Album/20%20-%20Hermes%20House%20Band%20-%20Portugal.mp3"
it can be played in 0.83 using foo_read_http.dll
but in 0.9or later it prompt this:

Unable to open item for playback (Not Found (404)):
"http://iris.trueice.net:8000/Songs/English/Misc/体育歌曲/The%20Official%20UEFA%20Euro%202004%20Album/20%20-%20Hermes%20House%20Band%20-%20Portugal.mp3"

any one can help me?

In 0.9.2 beta3 this problem seems to be solved.
