Is there a captcha available f开发者_高级运维or PHP which displays Chinese characters but isn't JavaScript dependent?
BotDetect captcha supports Chinese characters since the version 3.0 http://captcha.biz/localizations/chinese-captcha.html
A few days ago they released PHP version as well. http://captcha.biz/php-captcha.html
It works with JavaScript disabled.
