correctly and produces null characters in value
[ https://issues.apache.org/jira/browse/TIKA-887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13241134#comment-13241134 ]
Nick Burch commented on TIKA-887:
---------------------------------
Is the problem still present in Tika 1.1? Only there were some mp3 tag related fixes between 1.0 and 1.1 that may have solved this already

> I have a problem when extracting the comment tag from an MP3 file. It contains an invalid prefix then a '\0' character and then the real value of the tag. This happpens with files downloaded from www.jamendo.com, for example this one:
> http://storage.newjamendo.com/download/track/450545/mp32/Swansong.mp3
> It may be that the tags are not created properly on this site, but at least tools like mp3tag display them correctly.
> The extracted value looks like this: eng http://www.jamendo.com Attribution-Noncommercial-Share Alike 3.0
> At position 3 there is a null character. The tag value should start with http...
> Here is the byte sequence at the beginning of this file:
