Problem with UTF-8 in playlists (.m3u8 files)

[Manul]

Code:

reiter@pi:~$ locale
LANG=en_GB.UTF-8
LANGUAGE=
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=

Code:

reiter@pi:~$ grep -A 3 "^Minim" /opt/minimserver/data/minimserver.log

What I probably should have mentioned in my first post (sorry!) is that the music files reside on an ext4 file system mounted via NFS from a NAS (D-Link DNS-320L):

Code:

reiter@pi:~$ mount|grep platte
platte:/mnt/HD/HD_a2 on /platte type nfs (rw,noatime,vers=3,rsize=32768,wsize=32768,namlen=255,soft,nolock,proto=tcp,time​o=600,retrans=2,sec=sys,mountaddr=10.0.0.13,mountvers=3,mountport=48817,mountpro​to=udp,local_lock=all,addr=10.0.0.13)

From the NAS side:

Code:

reiter@platte:~$ mount|grep sda2
/dev/sda2 on /mnt/HD/HD_a2 type ext4 (rw,noatime,nodiratime,commit=30,data=writeback,barrier=0,stripe=96,usrquota,grp​quota)

There's no 'locale' command on the NAS, the only remotely related environment variable is

Code:

reiter@platte:~$ env|grep LANG
LANG=en_US

I've also attached the complete Minimserver log file to this post. That's all information I can think of at the moment, let me know if you need anything else.
