garbled code when the php page uses echo js code Question

When using php as the control script of the html front-end page, it is often necessary to display something in the foreground. For example, use echo output. There was such a requirement on a project recently. I used code like echo "3f1c4e4b6b16bbbd69b2ee476dc4f83a2cacc6d41bbb37262a98f745aa00fbf0". It was completely normal to debug locally. However, once it was deployed to the server, the js output to the front desk showed garbled characters.

After searching on the Internet, some people said that you can set 73ccd13e5f329ad85e64b9be25f58f092cacc6d41bbb37262a98f745aa00fbf0, but after setting it like this, I found that the problem still exists.

Analysis, the reason why the garbled code exists is that the page encoding is inconsistent with the browser display encoding, or that the front-end html page and the background control page encoding are inconsistent.

So, first set the PHP encoding and use the header function, header("Content-type:text/html;charset:utf-8"). Then refresh the browser and it will display normally. The explanation should be that the PHP encoding is inconsistent with the browser parsing page encoding.
