Re: [idn] Re: [idn-nameprep] Arabic hyphen-like glyph

["Soobok Lee" <lsb@postel.co.kr>]

Using hyphen in place of NWNJ in Arabic multi-word domains
may cause confusion because arabic script already contains
hyphen-like letters already. that's the point.
That's not related directly to nameprep, but to IDN security.

I hope those small ratholes may not become security holes in
IDN.
