By profiling the byte distribution of a file, it is possible to recognize different file encodings and even estimate the possible languages in which the text is written. A more mundane example of this could be given with our language. Taking as a symbol a word instead of a byte, if you analyze the entropy of a literary work, you will get an unknown entropy value X. Going back to FUN_080003e4 we can note that the addresses are no longer marked in red. Similarly let’s analyze the disassembly listing of any function (say FUN_000003e4) by clicking it on the symbol tree.
