Kind and gentle people who enjoy testing! Over on GitHub is an update to this plugin that has some hyphenation changes.
Technical details:
Because of the nature of the changes, I'd appreciate it if a couple non-English readers (representing a few different languages) could try out the new code and open issues on GitHub if you encounter hyphenation issues that were not previously present or if hyphenation simply doesn't work for your language. Ideally I'd like a language or two using Latin characters with accents (French, Spanish, etc.), Cyrillic characters (like Russian) and other glyphs (Japanese, Chinese) if hyphenation is normally available for those languages.
New hyphenation idea was a bust, turns out it didn't play nicely with languages using non-Latin characters. So, it's back to the drawing board to see if I can make the current hyphenation code play nicely.
