Re: [bug-libunistring] Joining_Type?

Indeed, IDNA2008 (= RFC 5890..5895) requires this [1]. I did not know
that this property could be useful to software that is not a rendering
engine. So it's really in the scope of libunistring.

I'm adding this patch to gnulib. It will show up in libunistring 0.9.4
eventually.
