Weird Autoit File

5 posts in this topic

I have an Autoit file that generates a unicode character everytime i open the source code as the first symbol.

I have no idea how it is possible, no other file does this. I can create muliple symbols by just saving the file with a generated symbol. 

Saving the file after deleting the symbol doesn´t fix the behaviour. I can copy the Source code and paste it into a diffrent Autoit file and its gone.

When i use the save as function the symbols stay with the file. The symbol is constandly switching after closing and opening, this is not the case if the editior window stays open because of another source code in this case the symbol is static.

Is this a possible bug in the Editor ? 

I Added the Autoitfile itself and 2 Screenshots.
Unlikly that you will be able to experice the behaviour of this unique file but the least we can do is try. 

I am using the SciTE Version 3.6.6 

and Autoit version 3.3.14

I don't get the issue you're having with that file, the file is encoded as UTF-16 LE which might have something to do with what you're seeing. Try a different encoding and see if it still happens.

 


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

you are right changing the encoding to UTF-8 removed the behavior too. 
The file is not making any real issues apart from me having to delete the unicode char every time i open the file.

I just this is weird behavior that i cant expain, maybe someone else can.

The file begins with 0xFFFE which you can check like this:

Local $hFile = FileOpen('C:\Users\Alexandra\Documents\what1.au3', 16) ; replace with your own file path

Local $data = FileRead($hFile)

FileClose($hFile)

MsgBox(0, "", $data)

Here is what Wikipedia has to say about this Unicode code point.

Quote

FFFE and FFFF are not unassigned in the usual sense, but guaranteed not to be a Unicode character at all. They can be used to guess a text's encoding scheme, since any text containing these is by definition not a correctly encoded Unicode text. Unicode's U+FEFF BYTE ORDER MARK character can be inserted at the beginning of a Unicode text to signal its endianness: a program reading such a text and encountering 0xFFFE would then know that it should switch the byte order for all the following characters.

This might give you some insight.
