CAUSE

This problem occurs if the following conditions are true:
The Web page uses a content disposition header to force Windows Internet Explorer 7 to download a file instead of opening the file in a browser window.
The file name in the content disposition header uses double-byte character set (DBCS) characters, such as Japanese characters.
The second byte, or "trailbyte," of any of the DBCS characters contains values that represent file system-reserved characters in ASCII. For example, the "trailbyte" contains values that represent ASCII values such as 0x5c or 0x7c.
When this problem occurs, the "trailbyte" is changed to a different value. Therefore, the DBCS character is altered.

Note DBCS characters use two bytes of memory to display a single character. This character consists of a "leadbyte" and a "trailbyte." These two bytes together determine which character of the target language is displayed.
