[X] MP3TAG adds random whitespaces to embedded cover art

[chrizoo]

As the topic title says ....

I have added a screenshot, so that you can see ... In the right panel is the original file, in the left one the file that has been tagged by MP3Tag (I only changed one letter in the artist name and saved the tag with MP3Tag).

You can barely see the difference, but the lines where the whitespaces are, are highlighted and the whitespaces are the red dots in the left panel:

You are probably using ID3v2.4 tags so this is called "Unsynchronisation" a feature of the ID3 standard. No bug.

Oh, I see. I just looked on the net.

Whenever a false synchronisation is found within the tag, one zeroed
byte is inserted after the first false synchronisation byte. The
format of a correct sync that should be altered by ID3 encoders is as
follows:

     %11111111 111xxxxx

And should be replaced with:

     %11111111 00000000 111xxxxx

I always took for granted that synchronisation refers to id3v2 and v1 tags being identical (as far as the common fields are concerned), but apparently I was wrong ... (?)
