Demonstrates how to control the URL encoding charset in POST query params.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// See Global Unlock Sample for sample code.

// We have the string "MÆRSK".
