Hello,
Suggestion: put the utf8 check code into a separated lpeg_patterns/utf8.lua ?
I supposed that having a way to check utf8 could be used outside of the iri support.

@tst2005 yeah I was thinking that. but I'm hesitating until I need to use it somewhere else: Returning codepoints as I have isn't very useful, and the range checks I have should be refactored before they become a public api (at the moment the utf8/ucschar pattern is not accessible directly)

@daurnimator No problem, I understand your choice ;)

I think I'll need to write bindings to libunistring or similar to get normalisation and case folding.
