Unicode in a VCL component

Q: Why I'm not able to send correct Unicode message from TEdit component? I have US/Western/Eastern European Windows and I want send Chineese/Hebrew/Arabic/Thai text message.

A: Standard TEdit visual component cannot handle current code page (ANSI) characters with characters not contained in ANSI CP. You should use 3rd party component, e.g. open source TNT visual controls (http://www.tntware.com/delphicontrols/unicode/).
