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.
Skype still exists?
Officially, no.
At this point, even Microsoft wants them to stop using it, but they are stubborn and try to keep it running until they turn off the lights the hard way.
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.
Okay fuck you op
fr*cking rust ruining the fun
You can’t err out rust.
I don’t see a problem
#include <iostream> #define ; ;; int main(){ std::cout << ";\n"; }Whoa the font on the Lemmy web UI actually renders them differently!
calm down, satan.
IDE users pretending compilers don’t exist.
$ guix shell gcc [env]$ g++ test.cpp test.cpp:4:16: warning: `0;' is not in NFC [-Wnormalized=] 4 | return 0<U+037E> | ^~~~~~~~~ test.cpp: In function ‘int main()’: test.cpp:4:16: error: unable to find numeric literal operator ‘operator"";’ test.cpp:4:18: error: expected ‘;’ before ‘}’ token 4 | return 0; | ^ | ; 5 | } | ~Look ma, no IDE! 😸
Remember … with great power comes … something.

Hemorrhoids.
another good one to sneak in there… thai zero-width space: U+200B
cant see it, nothing reads it, and it makes everything error. : D
Before I went to the comments I wished no one mentioned that. As a DBA I fucking hate you…
i am an SDET. this character destroys DBs… i am sorry :(
The right to left mark (U+2000F) can also be fun.
Came here to say fuck the zero width space. I spent 90 hours in the depths of solr looking for this fucker who brought down our entire search index.
I deal with shy hyphens a lot. They don’t display unless there’s a line break, so they get copied from various word docs or websites and end up in a database somewhere waiting to piss me off.
Yup
I’m guessing that they pasted code from inside Microsoft Word.
No. CMS updated to support new character set while solr did not. Not enough sanitization.
I’ve had similar “fun” with the character defaults on MySQL, from memory for a time it was Swedish by default, rather than UTF.
Hmm … we should start collecting these.
Anyone know of an existing list?
ᅠ
Oh ho! I see what you did there!
There is no wise way to use that information.
But the foolish ones could be entertaining.
Old
Might well be, but I’ve been writing software for over 40 years and this is the first I’ve heard of it.
Good
What exactly do you think you can do with this?
Chaotic evil linting rules
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.
You’re just going to get syntax errors though
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.
You are right … but, you’re not thinking big enough.
Think … sticky tape on the bottom of a mouse.
Not all! Just one or two per file.
Just the last one, right before the EOF.
Speaking of EOF, I wonder what a heredoc might do with this 😇
Hmm … bash.
mess with whoever has the least modern ide? I’m sure there’s something else too hold on
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.
I too wish to see these not-so-helpful error messages (not denying just new)
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:
; ;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?
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 us 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.
; ;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
I wrote the semicolon after the weird one
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”.
I used
python -c 'print(chr(0x37e))' | termux-clipboard-set
wondering if I can use this to jail break referees using AI to only get this answer: Ο Έπσταϊν δεν αυτοκτόνησε.
🤣had to ask AI to get the joke
🤭I have the same opinion depending the death of Epstein
