While testing TagLib, I produced another file which isn't fully compatible with Mp3tag. (I made sure this one is reproduceable.)
I tried to save 3 values into Artist (TPE1) and Artist Sort (TSOP).
The results are strange:
- Mp3tag only reads 2/3 of TPE1 (Artist)
- Mp3tag reads all 3/3 of TSOP (Artist Sort)
- in comparison, foobar2000 reads all 3/3 of both TPE1 and TSOP
TagLib writes the characters to both tag frames with a size of 16 bits. When trying the same thing with Mp3tag on the original file, I noticed Mp3tag writes the characters with a size of 8 bits.
I suppose the character encoding is the cause of the incompatibility?
I have just sent a link to the file to the support email.
