I want to add ...
Found this, related to PowerShell, the list of invalid chars seems to be complete.
PS \> "$($GetInvalidPathChars | foreach { [int]$\_ } )"
34 60 62 124 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
PS \> "$($GetInvalidFileNameChars | foreach { [int]$\_} )"
34 60 62 124 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 58 42 63 92 47
Regarding my example string ...
From
D:;\FOL_DER;\\..;A:?/_
now cleaned and canonicalized to
D;\FOLDER;;A.mp3
I noticed that the colon at position 2 was removed by Mp3tag v2.43c.
Does this work without failures under all circumstances that may come up in Mp3tag?
