Sorry, we cannot say exactly why it happens. The Skype developers may use customized version of TRichView with their own implementation of WM_GETTEXT.
(History:
Processing of this message was implemented in TRichView 1.9.6.
Starting from v1.9.10.2, processing of this message was disabled for Delphi 2005 and 2006, because it conflicts with their default implementation. I do not know which version of TRichView and Delphi Skype uses)

Skype devs use 1.9.14.1.

So, if they use an older version of Delphi (not 2005 or 2006), and they did not modify TRichView code, WM_GETTEXT should be processed by TRichView.
On this message, TRichView returns text using GetTextRange function from RVLinear.pas. This function converts Unicode text to ANSI (DBCS), using the language of style charset, or (if charsetr is DEFAULT_CHARSET)RVStyle.DefCodePage.
