While idn2_to_unicode_8zlz() takes a 'flags' argument, it is ignored and thus cannot be used to perform IDN checks on the output string. The bug in libidn2 versions before 2.0.5 was not that a call to idn2_to_unicode_8zlz() with certain flags set did not cause IDN checks to be performed. The bug was that idn2_to_unicode_8zlz() did not check whether a conversion can be performed between UTF-8 and the current locale's character encoding. In other words, with libidn2 version 2.0.5+, if the current locale's character encoding is ASCII, then idn2_to_unicode_8zlz() will fail when it is passed any Punycode string which decodes to a non-ASCII string, even if it is a valid IDNA2008 name. Rework idn_ace_to_locale() so that invalid IDNA2008 names are properly and consistently detected for all libidn2 versions and locales. Update the "idna" system test accordingly. Add checks for processing a server response containing Punycode which decodes to an invalid IDNA2008 name. Fix invalid subtest description. |
