?

Func _Offset2String($my_file, $start, $end)
  Local $file = FileOpen($my_file, 16)  ;$FO_BINARY
  Local $chars = StringRegExp(FileRead($file), '[[:xdigit:]]{2}', 3)
  FileClose($file)
  Local $txt = "offset " & $start & "-" & $end & " :" &@crlf&@crlf
  For $i = $start to $end
    $txt &= Chr("0x" & $chars[$i])
  Next
  Return $txt
EndFunc

Edit
Certainly much easier using FileSetPos

Alternative.
 

#include <FileConstants.au3>

ConsoleWrite(_ReadOffSet("1.txt",0,3) & @CRLF)
Func _ReadOffSet($sFilePath,$iOffset,$iLen=1)
    Local $sRet=""
    Local $hFile=FileOpen($sFilePath,$FO_BINARY)
    FileSetPos($hFile,$iOffset,$FILE_BEGIN)
    $sRet=FileRead($hFile,$iLen)
    FileClose($hFile)
    Return $sRet
EndFunc

Thx. Best way 4me FileSetPos.

And

ConsoleWrite(BinaryToString(_ReadOffSet(@ScriptDir&"\FontAwesome.otf",0x000000,16),1) & @CRLF)
