How do I fix the following segmentation problem: In Icelandic m.v. abbreviation is often followed by a date e.g. 'Ef misbrestur verður á greiðist sérstakt fatagjald kr. 12,53 á hverja klst. (m.v. 1.5.2015).' Although m.v. is in the abbreviation list it segments incorrectly after the v. when followed by a digit.
