I am using a very simple script that reads a random line from a text file and displays it in a message box when the hotkey is pressed.

The problem is that lines in the text file contain Greek and English words. When the message box appears, the Greek letters are not right:

άλογο - horse

instead of

άλογο - horse

How can I get the message box to display the Greek letters correctly? Please can somebody help me?

I don't believe AHK currently supports Unicode characters - see here

For example, copy this: άλογο - horse
Code:
MsgBox % Clipboard ; displays ????? - horse


Edit - also see How to Unicode//Ascii in a MsgBox???

The file is apparently saved in UTF-8. Save it as ANSI, e.g. in Notepad.

I hope you don't mind looking up the codes for unicode characters...

Code:
msgbox % MsgBoxW( 2, "{√Ⅹ∃}", "άλογο - horse" )

MsgBoxW( msg0, title="", text="" ) ; the "W" is for 'wide' chars
{ ; Function by [VxE]. A wrapper for the MessageBoxW function, which takes
; wide-char strings (unicode). Since AHK doesn't like unicode, the strings need
; to be converted (hence the A2W function).
; Before you ask... no, I don't know how to make it have a time limit
; function info @ http://msdn.microsoft.com/en-us/library/ms645511(VS.85).aspx
   static OwnerHWND, ResultList
   If !OwnerHWND
   {
      odhw = %A_DetectHiddenWindows%
      DetectHiddenWindows, on
      OwnerHWND := WinExist("Ahk_PID " . DllCall("GetCurrentProcessId"))
      DetectHiddenWindows, %odhw%
   }

   If !ResultList
      ResultList = OK,CANCEL,ABORT,RETRY,IGNORE,YES,NO,CLOSE,HELP,TRYAGAIN,CONTINUE,TIMEOUT

   If (title = "" && text = "" )
   { ; mode 1
      title := A_ScriptName
      text := msg0
      msg0 := 0
   }
   A2W( text )
   A2W( title )
   result := DllCall(   "MessageBoxW"
         , UInt, OwnerHWND
         , UInt, &text
         , UInt, &title
         , UInt, msg0   )
   Loop, Parse, ResultList, `,
      If (A_Index = result)
         return A_LoopField
   return result
}

A2W( byref str ) ; Ascii to Wide-char. Version 2.0
{ ; function by [VxE], returns a string in unicode format. Uses html-style
; codes for unicode characters (i.e. ሴ or 〹 ). Intended for
; external functions (via DllCall). Return value is the number of characters.
   text := str
   u := v := pos := 0
   Loop
      If (pos := InStr( text, "&#", 0, pos+1 ))
      && (pos2 := InStr( text, "`;", 0, pos ))
      {
         If (num := Abs("0" . SubStr( text, pos+2, pos2-pos-2 )))
         {
            u++
            u%u% := num
            StringReplace, text, text, % SubStr(text, pos, pos2-pos+1), % chr(4)
         }
      }
      Else   Break
   VarSetCapacity(str, 2+2*len:=StrLen(text), 0) ; make space and wipe bits
   Loop, Parse, text
      If (num := Asc(A_LoopField)) = 4
         v++, NumPut( u%v%, str, 2*A_Index-2, "UShort" )
      Else   NumPut( num, str, 2*A_Index-2, "UShort" )
   return len
}
