[emms-help] emms-cache-file coding system issue

[William Xu]

Hi folks, 

When enabling emms-cache module, i found my playlist buffer began to
display many garbages. After hunting for some time, i find it's caused
by the inconsistency between emms-info-mp3info-coding-system(it's 'gbk
here) and emms-cache-file-coding-system(the original value is 'utf-8, i
added this new variable in last patch). I can't simply set
emms-cache-file-coding-system to be same as
emms-info-mp3info-coding-system, since my file names are using utf-8
charset(which is also part of track structure, besides mp3info), a big
of mess...

Hence, seems i'm forced to do charset conversion if i want to use
emms-cache module. For a trivial solution, I wrap around `iconv' to do
conversions when emms-info-mp3info-coding-system is different from
emms-cache-file-coding-system. Things seem to be fine again.

What do you think?
