This is supposed to become an overview of support playlist formats in different players / music collection managers.

• i = import / play
• o = export
• x = plugin exists
• F = feature request

UTF-8 and file:/// URL support

One thing that come up with developing the file browser plugin is the varied support for file:/// URLs and platform-dependant UTF-8 encoding. This likely goes for direct-file invocation as well as playlist-contained references. Here grouped by samples:

App	version	platform	file:///	UTF-8
VLC	2.2.4	Windows 7	yes	syscp
Wmplayer	*	Windows 7	no	syscp
AIMP	*	Windows 7	no	syscp
MPC	*	Windows 7	no	syscp
*	*	Windows	partly	quoted
-	-	Linux	-	-
VLC	2.0.8	Ubuntu 12.04	yes	quoted
VLC	2.2.0	Ubuntu 16.04	yes	literal
Audacious	-	Ubuntu 12.04	yes	literal
Parole	-	Ubuntu 16.04	yes	literal
