The actual strings are quite a mess. I just wanted to know whether there's some issue with \b in Unicode. If you insist, then $string is something like

8^1589-20170113-102647-ויחי-דב&#15
+12;י_הספד_על_הר
+ב_משה_שפירא.mp3

and $_ is just 

שפירא

(it's hebrew, and I'm afraid your broweser might mess up the right-to-left presentation, or even just show the Unicode numbers instead of the characters themselves. My browser makes a mess here. That's why I didn't think posting the strings would help).
