Problem is your dash is a fancy unicode-y en dash, not just a simple "-" character so my naïve attempt's not matching. I had to do some monkeying with Encode cutting and pasting your sample (which I don't think you'd need for Mojo when you're actually fetching your real results) but then I was able to get this to match.

  ## I set $_ to your sample string cut-n-pasted, then ran it through 
+decode
  DB<33> $_ = Encode::decode( q{UTF-8}, $_ )

  ## Afterwards this worked (U+2013 is EN DASH); if you're not interes
+ted in what
  ## the separator was you can of course change that bit to non-captur
+ing
  DB<38> x m{ ^ (\d+) \. \s+ (.*?) \s+(-|\N{EN DASH}|\N{EM DASH})\s+ (
+.*?) $}x
0  123
1  'The Quick brown fox'
2  '\x{2013}'
3  'jumped over'
