I’m off on a tangent here, but I can add that when my native Swedish
uses single quotation marks it traditionally uses RIGHT SINGLE QUOTATION
MARK both before and after a quotation. This is yet another example of
how you need knowledge of the language, and yet another example of how
hard word-breaking can be.

Then if you read

        Jag såg ’na när hon spela’ piano.
      = Jag såg henne när hon spelade piano.
      = I saw her when she played the piano.

no simple algorithm would know that there isn’t a quote “na när hon
spela” in there.
