Russian Localized CAPTCHA Images

Example Captcha images generated by BotDetect using the base Cyrillic character set for all Captcha ImageStyle values can be seen in the BotDetect Captcha image styles demo

To use BotDetect Captcha images localized for the Russian Captcha Locale in your application, you can specify the Locale value:

  • In PHP applications, you can use either the application-global setting in the lib/botdetect/CaptchaConfig.php file:
    // Set the default Locale for all Captcha instances in the 
    // PHP application to Russian
    $LBD_CaptchaConfig->Locale = 'ru';
    or the Captcha object instance-specific value:
    <?php 
      $SampleCaptcha = new Captcha("SampleCaptcha");
      $SampleCaptcha->UserInputID = "CaptchaCode";
      // Set the Captcha object instance Locale to Russian
      $SampleCaptcha->Locale = 'ru';
      echo $SampleCaptcha->Html(); 
    ?>
  • In ASP.NET applications, you can use either the .aspx page source:
    <!-- Captcha control localized to Russian -->
    <BotDetect:Captcha ID="SampleCaptcha" runat="server" Locale="ru" />
    or the page code-behind:
    [C#]
        
    // Set the Captcha instance Locale to Russian    
    SampleCaptcha.Locale = "ru";
    [VB.NET]
        
    ' Set the Captcha instance Locale to Russian    
    SampleCaptcha.Locale = "ru"

    Locale-dependent Captcha strings can be configured in the <botDetect> Web.config configuration section.

  • In ASP Classic applications, you can use either the application-global setting in the BotDetect\CaptchaConfig.asp file:
    ' Set the default Locale for all Captcha instances in the 
    ' Classic ASP application to Russian
    LBD_Configuration_Locale = "ru"
    or the Captcha object instance-specific value:
    <%
      Dim SampleCaptcha : Set SampleCaptcha = (New Captcha)("SampleCaptcha")
      SampleCaptcha.UserInputID = "CaptchaCode"
      ' Set the Captcha object instance Locale to Russian
      SampleCaptcha.Locale = "ru"
      Response.Write SampleCaptcha.Html
    %>

Russian Localized Audio CAPTCHA Sounds

Example audio Captcha sounds generated by BotDetect using the Russian Locale setting can be heard in the BotDetect Captcha features demo

To use BotDetect sounds localized for the Russian Captcha Locale, you should also download the Russian Pronunciation Sound Package and deploy the .bdsp file to the BotDetect sounds folder your application uses:

  • PHP applications always use lib/botdetect/Resources/Sounds.
  • ASP.NET applications use Bin\BotDetectSounds by default. A custom folder can be specified in the <botDetect> configuration section.
  • ASP Classic applications use Redistribute\BotDetectSounds in the BotDetect installation folder by default. A custom folder can be specified in the BotDetect/CaptchaConfig.asp file.

Russian Localized CAPTCHA Codes

The ru-RU Captcha locale uses the default Cyrillic character set, consisting of 25 characters.

Unicode Captcha Codes and Font Requirements

This table on the left uses the actual Unicode characters drawn in localized Captcha images.

Displaying these characters in your browser requires having fonts which support them installed on the client machine.

In ASP.NET and ASP Classic versions of BotDetect, generating localized Captcha images using these characters also requires supporting fonts on your server.

If viewing these characters in your browser or generating them in Captcha images on your server fails, you can enable the required localization support for on both client and server machines using Control Panel:

Windows 2000, XP, 2003 Server: Regional and Language Options → Languages → Supplemental language support.

Windows Vista, 7, 2008 Server: Region and Language → Keyboards and Languages → Install/uninstall languages.
