Copyright Reference in Code Crashes Browser

I have a simple HTML page that posted just fine a year ago. But now it crashes browsers, and it took me some time to finely isolate the particular line of code that was the problem: it is the copyright reference in one tag. There’s another copyright reference below it, but visibility is turned off for that div so that keeps it from being a problem. Running the pages locally in the browser is NOT a problem. Running them on a server (and I’ve tried two different ones) creates the browser crashing.

<p class=“copyright”>Any text works here as long as I don’t start with “Copyright”, “©”, or “©”</p>
