A client of mine has a problem uploading to my system, and from what I can tell is his file that has the name corrupted (it is relatively common, on Windows systems, the name or accented with foreign characters display correctly in Windows Explorer but when you try to access it programmatically character encoding error occurs). Unfortunately, when it is emailed to Gmail please fix the error in the name automatically, so I can not reproduce the error in my environment ...
Is there any relatively simple way to e-mail a file so that its name (including any encoding errors) is preserved? Preferably something that does not require much technical knowledge, that I can simply tell my client "do X, then Y, and send me the result".
Update: In my particular case, the problem was elsewhere, so I no longer need a response with no urgency. But I will keep asking the question, as this is a problem I have faced before, and a response can be helpful when trying to debug encoding problems remotely (when it is costly to go to the client to get the file straight from the his machine).
