Can some one please explain me how lazarus prints characters in a
TComboBox component?
 I have problems listing cyrylic text in the combobox, whel loading it
from file with the LoadFromFile function.

I am not on a computer that has Lazarus so I can only give some
suggestion.  I think it is a problem of Encoding.  If you have
Notepad++ or something like it, you can open the text file and check
what Encoding.  You can also type text into ComboBox and save to
file.  Open ComboBox file with Notepad++ and check Encoding.  This
might help you find the right path.

Lazarus always use UTF8 encoding. The text in your file is probably
encoded differently.
Add LConvEncoding unit to your uses list. This unit contains function
for conversion between different character sets. Find out which
encoding is used in your file and use appropriate function (probably
CP1251ToUTF8).
However, then you cannot use LoadFromFile directely, but you can use
auxiliary StringList:
Code: [Select]uses
  ..., LConvEncoding;

...

procedure TForm1.LoadTextInComboBox(FileName: String);
var
  SL: TStringList;
begin
  SL := TStringList.Create;
  try
    SL.LoadFromFile(FileName);
    ComboBox1.Items.Text := CP1251ToUTF8(SL.Text);
  finally
    SL.Free;
  end;
end;

My encoding is ANSI
I used AnsiToUtf8 function
Then it worked perfectly, but when I moved the project and the SAME
text files on another computer, the same problem appeared.

Ansi means this: The encoding of the system where the application is
running. So obviously it changes from computer to computer.

Why didn't you use the solution pointed by Zoran?
