Did one of your annoying nerdy friends hide some weird unicode in a message they sent to you? Copy/paste into this site to see exactly what dickery they're up to:
https://babelstone.co.uk/Unicode/whatisit.html
I say this because I'm that annoying friend that likes to slip a unicode right-to-left character in just to see what happens.
Can you give an example of the kind of dickery one might get up to by hiding Unicode in a message? I’m not sure I understand what this is for
You can reverse the way characters display with this unicode character. U+202E. Example. You can use this to make users think that a file has a different exnetion that it really has. Example: image.gnp.exe This example actually has the extension.exe so it is a executable but looks like it is a PNG.
Also, at an old workplace I put that in my username in our chat app and it completely screwed up the UI for people that were using terminal apps for chat as soon as my username appeared and I had to take it out.
You can also do things like use confusable characters to point someone at the wrong domain like pаypal.com.
Pretty cool story. Thanks for the site looks interesting.
