What is this strange symbol?

Question

PHP

When receiving a page from the server, an incomprehensible symbol appears which is not on the server in the code, but is in the browser. And most importantly, because of it, the layout is very floating = (
here it is:

when you open the source code of the page (in the browser alt + cmd + u), it (symbol) is not there

, but if you copy and paste this code into the Sublime Text editor, it becomes visible

I tried to find it from the server side, passing through var_dump everything that I send to the client, but there is no sense =(

Answer 1

Sorry for disturbing. Issue resolved. A strange symbol appeared due to the transfer from one server to another. During the transfer, the controller file that collected the page was damaged (but somehow strange), it retained its contents, and the checksums were different. In general, reloaded it and everything became normal. Magic...

Answer 2

Maybe your layout is floating not because of a strange symbol, but because you are closing a non-existent dir tag there ?
