Bulgarian 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 Bulgarian Captcha Locale in your application, you can specify the Locale value:

In ASP.NET applications, you can use either the .aspx page source:

<!-- Captcha control localized to Bulgarian -->
<BotDetect:Captcha ID="SampleCaptcha" runat="server" Locale="bg-BG" />

or the page code-behind:

[C#]
    
// Set the Captcha instance Locale to Bulgarian    
SampleCaptcha.Locale = "bg-BG";

[VB.NET]
    
' Set the Captcha instance Locale to Bulgarian    
SampleCaptcha.Locale = "bg-BG"

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 Bulgarian
LBD_Configuration_Locale = "bg-BG"

or the Captcha object instance-specific value:

<%
  Dim SampleCaptcha : Set SampleCaptcha = (New Captcha)("SampleCaptcha")
  SampleCaptcha.UserInputID = "CaptchaCode"
  ' Set the Captcha object instance Locale to Bulgarian
  SampleCaptcha.Locale = "bg-BG"
  Response.Write SampleCaptcha.Html
%>

Bulgarian Localized CAPTCHA Sounds

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

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

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.

Bulgarian Localized CAPTCHA Codes

The bg-BG Captcha locale uses a modified version of the Cyrillic character set, without Я.

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.

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.
