language switch changes rules?

Found three small issues, all related to different behaviour when processing greek characters, instead of latin.

Problem 1: single quote before space

correctwrong


inputenglish' englishελληνικά' ελληνικά


outputenglish’ englishελληνικά′ ελληνικά

Problem 2: double quotes before full stop

correctwrong


input"english"."ελληνικά".


output“english”.“ελληνικά“.

Problem 3: double quotes before comma

correctwrong


input"english","ελληνικά",


output“english”,“ελληνικά“,
