Filename is corrupted in Live Messenger?

[Ravanx]

The full name of the file isn't THEFRA~1.MP3 (not all letters are capitalized and there is no ~ dash in the actual filename)

Yet when sending some files over Windows Live Messenger, the filename is not correctly shown within the chat window some times (not every time; sometimes, the filename is shown correctly).

What is causing this error?
