           Summary: icydemux's charset mangling functions not workable for
                    non-UTF-8(?) streaming radios.
           Product: GStreamer
           Version: 0.10.12
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED

          Priority: Normal

Please describe the problem:
When I play a streaming station with the istream panel applet, I can see songs'
title shown with unreadable characters.

My system's LANG is en_US.UTF-8, and the station I played usually broadcasts
Korean(mostly cp949 tagged) songs. I know there is no charset info on the
stream to begin with because it's usual case by shoutcast and icecast
streamings - the info is conditional by spec. But, because I can guess those
songs tagged with Korean, starting istream given with LANG=ko_KR.euckr brings
song's title look OK.

But, problem is with normal starting of the istream, this is because, I looked,
that icydemux's magling functions try to convert,
1) $LANG to UTF-8
2) iso8859-1 to UTF-8 if 1) failed.

As you may see now, 1) mine is already UTF-8 and it doesn't match with song's
tagging charset(cp949) either, 2) makes more trouble - cp949 can't be
iso8859-1.

I think, this is a common problem to at least for CJK (Chinese, Japanese and
Korean) users who use their UTF-8 system and listen streaming station running
on Windows so maybe already filed for bug. But, I am new here and this is my
first bug report to Gnome so wasn't familiar to check duplications. 


Steps to reproduce:
1. install the istream panel applet
2. edit ~/.istream file to add this entry to top, mukulcast
(KPop)=http://mukulcast.com
3. play the mukulcast, after openings you will see unreadable song's title for
Korean. 


Actual results:
Title of songs can't be readable for Korean.

Expected results:
No matter I start the istream applet with or without LANG env set, the title
should be readable for Korean.

Does this happen every time?
Yes.

Other information:
I looked, http://bugzilla.gnome.org/show_bug.cgi?id=428689 
this patch maybe targeted for files, but the idea of the patch generally fix
this problem too if it's for icydemux, I believe. Somewhere need to manually
store preferred charset for conversion, since currently no valid charset info
provided by LANG nor streaming for this reported case.
