Korean Localized CAPTCHA Images

Example Captcha images generated by BotDetect using the base Hangul 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 Korean 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 Korean
$LBD_CaptchaConfig->Locale = 'ko-KR';

or the Captcha object instance-specific value:

<?php 
  $SampleCaptcha = new Captcha("SampleCaptcha");
  $SampleCaptcha->UserInputID = "CaptchaCode";
  // Set the Captcha object instance Locale to Korean
  $SampleCaptcha->Locale = 'ko-KR';
  echo $SampleCaptcha->Html(); 
?>

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

<!-- Captcha control localized to Korean -->
<BotDetect:Captcha ID="SampleCaptcha" runat="server" Locale="ko-KR" />

or the page code-behind:

[C#]
    
// Set the Captcha instance Locale to Korean    
SampleCaptcha.Locale = "ko-KR";

[VB.NET]
    
' Set the Captcha instance Locale to Korean    
SampleCaptcha.Locale = "ko-KR"

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 Korean
LBD_Configuration_Locale = "ko-KR"

or the Captcha object instance-specific value:

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

Korean Localized Audio CAPTCHA Sounds

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

To use BotDetect sounds localized for the Korean Captcha Locale, you should also download the Korean 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.

Korean Localized CAPTCHA Codes

The ko-KR Captcha locale uses the default Hangul character set, consisting of 26 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.
