Uploads break on Unicode filenames

[Matt Giuca]

If a file is uploaded (inside a Zip file) with a Unicode filename, any non-Latin-1 characters will show up as "?". Latin-1 characters appear to work. "café" shows as "café", whereas "一個文本文件" shows as "??????.txt". Interestingly, it has the correct number of characters, so I don't know what the deal is.

Running the exact same Zip code from the command-line, reading from stdin, it works perfectly, and gives well-formed Unicode strings. So I suppose it has something to do with the encoding of the input stream. (But I thought InputStream was a binary stream and didn't have any encoding.)
