Apostrophes are replaced with quotes in non-latin words

I'm currently creating a website that has content in Ukrainian language. This language uses Cyrillic alphabet and has words that contain apostrophe (e.g., розв'язок). Typography doesn't recognize single quote in this word as apostrophe and replaces it with double quote, so the word becomes розв“язок instead of розв’язок. I checked the code of the module and found out that some regexps that contain \p{L} don't have a u modifier. I added it and now the apostrophes are recognized properly. The patch is attached.
