PlayList format and translation

Sandisk Sansa mp3 player may have playlists of mp3 files.  These files are stored in \PLAYLIST.
The format of playlist is actullay in UTF-16LE.  In order to translate it to an ASCII (UTF-8) format, we can use a command line tool in Unix/Linux (available in Cygwin for Windows too).

Here's an example how to convert a playlist to a text format:

bash-3.2$ iconv -f UTF-16LE -t UTF-8 playlist.pla

To create a playlist, we just reverse the format and redirect the output to a file (with extension pla) and then copy the generated file to Sansa's PLAYLIST folder.  Just to remember, the path of each file is relative to MUSIC folder.
