    Pretty much any ide will spot that. Maybe you can use it to teach your colleagues not to use a plain text editor.

      In VSCode (yeah yeah MS bad, I have to use it for work) it puts a yellow box around the charcater, which I don’t immediately recognize the meaning of and highlights the line as “identifier “blah;” is undefined”. It’s not like your gunna spend all day on it, but that could waste a couple minutes if the dev wasn’t paying close attention, which is “fun prank” territory.

        Can you choose to use VSCodium instead? It’s practically identical, but isn’t controlled by MS.

          The reason it’s de facto mandatory is due to some in house extensions, assuming they work with this I could, but I also don’t particularly care about my privacy on a work machine. But I will be checking this out for my personal stuff!

            The extensions should work still. It even still integrates with the same extention marketplace. It’s the same software, just the open source part without the MS stuff —which honestly, I have and do use both and I don’t know what the difference is.

            It’s definitely worth checking out. If it doesn’t work for you then still nothing is lost except a small amount of time, but I’m willing to bet it does.

      I mean sure, but it’ll still likely leave 'em scratching their heads for a while before they go “I guess I just… replace the semicolon…?”

      Tried to figure out which was which by googling, but it seems they are both read as semi colon, however you can see the difference in the characters. Wild

          If you look at the UTF definition, it seems that there are at least four of them. The weird one in your comment might actually be one of the other two because as far as I can tell, the “Greek Question Mark” looks identical to the “semicolon”.

    With the “wonderful” tooling at work, we use Skype for Business. Naturally, that is not the primary place to send around code and configs, but a 1-liner or 2-liner happens.

    You can’t believe the nonsense it does when you try to copy & paste it. Spaces get turned into non-breaking spaces etc. Looks completely normal when pasted directly into vim on a console, but will give “odd” error messages.

    Any half-decent editor/IDE/command line tool will scream at you about this; plus there’s version control which should help you spot it as well.

    Wow!

    This seems to be further evidence that the process for assigning UTF entities has been thoroughly corrupted.

    You can (apparently) copy/paste this on mobile:

    “;” (Greek question mark)

    “;” (Semicolon)

    You can even render it in HTML:

        &#894;
    &#x37E;

    And it’s included on Wikipedia, because of course it is:

    Because I’m not sure what my mobile client will actually do with this comment, here’s the link to the HTML entity I used:

    Also there’s plenty of other character joy to be had:

      If I don’t understand what’s happening here but want to, should I research Unicode in general or something else?

      • Onno (VK6FLAB)

        Unicode is a way to encode the things that humans use to write stuff into a computer.

        ASCII is for example another way, as is EBCDIC.

        All these methods translate squiggles that we’ve used for centuries into something that can be represented inside a computer.

        For example, the letter “A” is under ASCII represented by the number 65.

        This post is pointing out that there are two characters that look identical, but have different numbers, which means that what the user sees is identical, but what the computer sees is different.

        This is the basis for much tomfoolery.

          This fact is actively used for phishing, as you can craft domains looking nearly identical to the original one, but leading to your IP address hosting the phishing mask.

            One of my favorites was using Japanese full stop (U+3002) in place of periods in a bare IP or anywhere you would use a period in a FQDN (fully qualified domain name). Only tested in Chrome at the time, but the browser would “correct” it for you and take you to the intended page.

      Take someone’s source code, replace all semi colons with Greek question marks and see if they can compile. But as others said, any IDE will help.

          Just the last one, right before the EOF.

          Speaking of EOF, I wonder what a heredoc might do with this 😇

          Not if you choose to replace the correct ones at the correct place and it is a compiler which automatically ignores this wrong semicolon.

          You could connect two lines, which may still “work” if not split using a semicolon and are then interpreted as one single line.

        Would probably be more effective to mess with Linux config files that use semicolons. Especially if it’s run as a daemon because Systemctl doesn’t always return helpful error messages for configuration errors.

          I think most daemons would log a helpful enough error message regarding incorrect syntax e.g. if it’s a config file of variable=value; format then it wouldn’t expect two equals signs on the same line.

          would you say openRC or rc-service returns better or more helpful error messages with these kinds of things?
