Playlist issues

[vodanh]

1) Playlist function doesn't save unicode/foreign file names correctly, as a result, it can not play it's own generated playlist after being saved.
(It has no issues playing the files in the playlist window.)

SMPlayer generates :
#EXTM3U
# Playlist created by SMPlayer 18.10.0 (revision 9144) (64-bit)
#EXTINF:176.081,A-Lin - ???? - ?????«????»( “How Far I’ll Go” From “Moana”) - YouTube.mkv
A-Lin - ???? - ?????«????»( “How Far I’ll Go” From “Moana”) - YouTube.mkv
#EXTINF:0,So-Hyang - ??? ???-“How Far I’ll Go”(??? ????) -??.mp4
So-Hyang - ??? ???-“How Far I’ll Go”(??? ????) -??.mp4

When I load a correctly generated playlist from MPC-BE it plays fine on SMPlayer.
MPC-BE generates:
#EXTM3U
C:\Users\Default.DESKTOP-G62KN71\Desktop\A-Lin - 海洋之心 - 迪士尼電影《海洋奇緣》( “How Far I’ll Go” From “Moana”) - YouTube.mkv
C:\Users\Default.DESKTOP-G62KN71\Desktop\So-Hyang - 디즈니 모아나-“How Far I’ll Go”(언젠가 떠날거야) -소향.mp4

2) SMPlayer can't seem to recognize this playlist generated from VLC player in m3u format. It doesn't seem to recognize that they're folders and it needs to go deeper into subfolders to play the files. ( Would be nice to support, but I understand if its out of the scope of playlist support because VLC does something nonstandard). No log file is generated for this, no error messages either. It just doesn't play anything.
