Hi All,
When I try to use the following code in the KeyPress event of the
form;
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.FormKeyPress(Sender: TObject; var Key: char);begin 
Caption:=Key; // ÇĞİŞÜÖ--> ?end; For unicode characters I get the
character ?.

In the KeyDown event, I get the numeric number of the key directly.
Can I solve this without dealing with numeric numbers, that is,
without entering the KeyDown event?

Char only supports single Byte characters, thus larger Unicode
characters can never be handled with OnKeyPress. You need to handle
OnUTF8KeyPress instead.

It was very sad not to think about it.
