Bug ID: 63216 Summary: Only accept CAPTCHA responses with diacritics removed Product: MediaWiki extensions Version: unspecified Hardware: All OS: All Status: NEW Severity: normal Priority: Unprioritized Component: ConfirmEdit (CAPTCHA extension) Assignee: wikibugs-l@lists.wikimedia.org Reporter: m...@1ec5.org Web browser: --- Mobile Platform: --- With a fix for bug 5309, such as the one discussed at <https://gerrit.wikimedia.org/r/121255/>, it’s entirely possible that a user might get a CAPTCHA with illegible diacritics. Diacritics in Latin alphabets can look identical to one another when distorted, for example i í ì ỉ, or ó ơ. For better usability, ConfirmEdit should display a CAPTCHA containing diacritics but require the user to enter the characters without diacritics. There’s a third-party module called Unidecode that does a decent job of accent folding. One tradeoff would be that such CAPTCHAs might be easier for a bot to crack. There’s also the issue that a character like Ê might be considered a base letter in one language (as in Vietnamese) but a letter with a diacritic in another (Portuguese). -- You are receiving this mail because: You are the assignee for the bug.
