I have other things to do, so I can't play with it right now and someone of you might know and gain some credibility points here. So, the question is:
There are extensions for Unicode that allow the testing of characters by properties. For example \p{L} would match any character that is categorized as a letter in any script. Does the regex engine that nginx uses support theses expressions? The nginx docs do not seem to mention anything in this regards.
