I got some special characters in my codes, take a look at:
a
It's just shown in frontend with normal characters like an "a". Now the same characters without any normal characters:
Characters starts here
Characters ends here
Ok it looks like this Editor will not save empty , try it with snippet.
<html><p>
</p></html>The problem is, in PhpStorm this characters wont be shown, even not with
"settings - Editor - General - Appearance - show whitespaces" or
"settings - Editor - General - Appearance - show method separators"
Only "strg+f, strg+r" will find this characters.
I think this character is an "only-mac-char" :) I'm working with Windows, and I can't test it on mac.
EDIT: Sorry i could identify it as "U+2028 : LINE SEPARATOR" http://www.babelstone.co.uk/Unicode/whatisit.html
The big problem is that phpStorm didn't show anything in the code. Like there is no character, but moving with the arrow keys notice 2 steps at this position, between 2 tags looks like "><" but it's "> <".

How to show tabs and white space characters in IDEA? To enable this feature in IntelliJ, you must open the Settings dialog ( Ctrl+Alt+S ) and navigate to the Editor | General | Appearance tab. In this tab you need to enable the Show whitespace option.
Basically, it's the guide line showing where the wrapping will occur (if enabled for certain code constructions).
Based on your update it is now clear what character you have in mind:

Install and use Zero Width Characters locator 2 plugin: it can detect quite a few invisible characters (e.g. UTF-8 BOOM sequence, non-breakable space, Unicode line separator (your case) etc).
It is implemented as a separate inspection with highest (Error) severity so will be easy to spot or check the whole folder/project just for these issues.
There is a ticket (Feature Request) to have an option to show invisible characters in the editor.
https://youtrack.jetbrains.com/issue/IDEA-115572 -- watch this ticket (star/vote/comment) to get notified on any progress. implemented in 2020.2 version.

UPDATE 2021-11-10:
