Package: lltag
Version: 0.14.2-1
Severity: normal
The encoding of the data that is put into the ID3 tag depends on the system
locale, even if the data was fetched from a freedb.org server. However, the
charset in the ID3 tag is always set to "latin1".
Example:
---------------------------------------------------------------------------
$ lltag --mp3v2 --cddb *.mp3

Now, lets see what is written into the ID3 tags, with a reliable tool
(eyeD3):
------------------------------------------------------------------------------
$ eyeD3 --debug 07\ -\ Parties\ in\ München.mp3

-----------------------------------------------------------------------------
As you can see, UTF8 data was written into the tag, but the encoding was
specified as latin1, resulting in corrupted data (München vs. München). My
system locale is set to UTF8:
$ locale | grep LC_CTYPE
LC_CTYPE=de_DE.UTF-8
The UTF8 text in the ID3 tag is doubly wrong here, because an ID3 V2.3 tag
is written, and v2.3 doesn't even support UTF8 encoding, only UTF16, but
this is a libmp3-tag-perl bug.
Now, I'll do this again with the locale charset set to latin1:
-----------------------------------------------------------------------------
$ LC_CTYPE=de_DE lltag --mp3v2 --cddb *.mp3

perl: warning: Please check that your locale settings:

Now the tag data is correctly encoded.
So lltag garbles the data fetched from a cddb server depending on the system
locale, which is very strage behaviour I think.
