How to remove the character ?

Question

Character encoding

There is a php file. Notpad shows utf-8 file encoding without BOM. On the Internet it is written that with this encoding there should not be a character . But the character remains in any encoding, be it UTF-8 or UTF-8 without BOM. I don't know how to solve the problem.

Answer 1

There are several options:
0. You need to make sure that this particular file is opened, directly, and not some other file connects this one, or this file connects some other one (as a result of which this symbol appears)
1. Change the editor to some other, for example: VisualStudio Code, Atom, Notepad (WIndows) or GEdit (Linux), vi(m)/nano, Atom and others. See how things are in this editor, if the same - try changing the file encoding to single-byte (for example, cp1251) and check the results.
2. Create a new file (empty), and check that everything is fine with it and this symbol is not there, then transfer the code from the old file to this one.
3. Make sure that you don't have any proxies that can (for some reason) insert this character (this is of course already somewhere close to paranoia, but still, for example, NodeJS sometimes selectively spoils the encoding when acting as a reverse proxy )
4. If none of the above helped - call an exorcist priest to expel evil spirits from the computer or (alternatively) send this court file.
