if the image tag is drawn dynamically then it is actually probably less bandwidth than the unicode character since the image can be cached at multiple locations including the browser.

- cure 5y ago.... no way. Cache freshness checks involve a lot of headers, which take up way more bandwidth than one unicode character.
- jermaustin1 5y agoif you care about cache freshness - you could set the cache header to 10 years and it never be an issue again.
- jrochkind1 5y agoLess bandwidth than the 1-4 bytes of a codepoint in UTF-8? How do you figure?
- jermaustin1 5y agoBecause if it is cached, then it is 0 bytes transferred. First request could be probably a few hundred bytes, but never needed again. And once it is at a CDN, there is never another request to the server.
