Minified builds do not work in some circumstances

See original GitHub issue

Minified builds found on CDN’s do not work. They produce errors related to emojione.

example

<html>
<head>
  <link rel="stylesheet" type="text/css" media="screen" href="https://cdn.conversejs.org/3.3.2/css/converse.min.css">
  <script src="https://cdn.conversejs.org/3.3.2/dist/converse.min.js"></script>
</head>
<body>
  <script>
      converse.initialize({
          bosh_service_url: 'https://conversejs.org/http-bind/', // Please use this connection manager only for testing purposes
          show_controlbox_by_default: true
      });
  </script>
</body>
</html>

result in chrome

workaround

Do not use minified builds

suggested temporary fixes

stop building broken minified builds for the CDN
stop using broken minified builds in the documentation, specifically where it is likely to confuse newbies like me: https://conversejs.org/docs/html/quickstart.html#getting-a-demo-up-and-running

ideal fix

report upstream to the minify vendor.

Hope that’s enough data. I nearly gave up adopting this 2 hours after finding it, because it was hard for me to debug given lack of familiarity with the project.

I confirm this issue. <meta charset=utf-8> fixes running the minified version for me. I use another charset, and the minified version is somehow incompatible with mine.

The error looks like something feed UTF-8 data into a parser expecting Latin1. There doesn’t seem to be any encoding specified on the HTML data from those pages on hashbang.info, nor from the CDN. Possible cause? See if adding <meta charset=utf-8> appears to fix it.
