No IDN validator is an extension for Contao Open Source CMS.
This extension provides two validators to Form generator:
- E-mail address without IDN
- URL format without IDN
Theses validators are different from standard "E-mail address" and "URL format" in that they don't handle IDN (Internationalizing Domain Names).
Standard validators decode IDN to ACE (ASCII Compatible Encoding) before validate it, but there is a case IDN wouldn't be acceptable. So I started to write this extension while I submitted the ticket to request a feature for Contao (http://dev.contao.org/issues/2749) and it was rejected instantly. :-)
(Yes, I feel it is somewhat negative idea as fo I18N, but sadly it is still needed by "the real world" yet.)
