Specifies the character code of the pressed key.

This method receives the WM_UNICHAR notification, which is described in the Windows SDK. The WM_UNICHAR message is designed to send or post Unicode characters to ANSI windows. It is equivalent to the WM_CHAR message, but uses Unicode Transformation Format-32 encoding (UTF-32), whereas the WM_CHAR message uses UTF-16.
This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
This method is supported in Windows Vista and later.
Additional requirements for this method are described in Build Requirements for Windows Vista Common Controls.
