_HexToString giving a different result than an online converter...

[theguy0000]

I doubt anyone will want to read this complicated problem, much less help, but here goes.......

#include <String.au3>
$contents = String(FileRead(@MyDocumentsDir&"\Untitled.pdf"))
ClipPut ($contents)
$contents = _HexToString (StringTrimLeft($contents,2))
MsgBox (0, "", $contents)

Ok, so...I read the pdf file, and get this:

%PDF-1.3

I perform String ( ) on that to get a very long string of hex (starting with 0x).

On line 3 of the script, this hex string is copied to the clipboard.

When I paste the hex from the clipboard and into the decoder here, I get a longer string which I cannot copy to the clipboard for some reason, try it yourself with the hex:

Ok, so that's fine. Now How can I get that into my AutoIt Script? Well, the first thing that should come to mind is _HexToString ( ). Right? of course, that's what the online converter did right? so _HexToString should do the same thing. Well, it doesn't.

_HexToString of the same hex used on the site, gave this when using _HexToString:

look farmiliar? Of course it does! It's the same Text originally read from the file in the first place!!

Why on earth is _HexToString giving a different output than an online Hex converter?

ConsoleWrite(BinaryString('0x' & $s))
;The above translated correctly

hmmmm, all of those gace me the same result, except one. The one that you said converts to hex. That one actually does convert to hex.

Ok, so I got hex. pretty good so far. Now, the problem is translating that hex to text.

The online converter mentioned in my first post works great. But, performing _HexToString with the SAME hex string, _HexToString gives me a different result than the online converter.

Any idea why?

I had the same result as the online converter you mentioned when I converted using the Hex part and then the BinaryString('0x' & $HexCode)... so no, I have no idea.

Actually, I have no idea what you think the output is supposed to be.
