[BUG] - MediaScannerService Crashes Parsing Characters

[funkmata]

Version 6.0 (build a7857c) – April 30, 2016
Server jetty-6.1.x, java 1.8.0_111, Linux (73.8 MB / 133.5 MB)
Uname Linux x.x.x 3.10.0-514.2.2.el7.x86_64 #1 SMP Tue Dec 6 23:06:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

BUG: Subsonic's MediaScannerService completely bombed out when it attempted to parse one of my mp3's that had the 'Σ' character in the filename and id3 tag title. See the error below in /var/subsonic/subsonic.log

Should be easy to replicate. Just add the 'Σ' to a song's filename and id3 tag title and run a scan. The user will only notice the error when new albums are added to their media collection and only a few songs are visible (because the MediaScannerService crashes before it has a chance to scan them all in).
