Description Andrea Ippolito 2024-06-27 08:16:46 UTC 
I connected my Pixel 8 Pro to copy some (MP3) music from Dolphin.

When the copy process reaches certain files, it hangs indefinitely. Canceling the process also makes the MTP device no longer usable until it's disconnected and reconnected.

I tried to isolate the problem, and the files causing all contain some special characters. The ones I could confirm to be causing trouble are `?`, `:`, `"`

Weirdly enough, if I try to transfer a dummy TEXT file instead (containing one of those chars), I get immediately a popup informing me the file cannot be transferred.

This is not the case when transferring MP3s, though. Even if I try to transfer just ONE MP3 containing one of those characters, the copy still starts without any warning, and hangs.

If I expand the ongoing copy notification, I can see that the target file name contains the special character as an URL-escaped sequence (e.g. `%3F` for `?`)
