Question

Sometimes when I copy javascript from jsfiddle into Dreamweaver I end up banging my head in the wall. Two documents with (what looks to be) the EXACT same javascript doesn’t work in the same way.

In document A I have the following code:

<script>
alert('test')
</script>

In document B I have the following code (does not work):

<script>
alert('test')
​</script>

Note: Please copy code B in to a html document and try if it alert before giving me comments. I am not joking, there is something weird going on.

I have located the problem to be something with the end script tag, but I can’t see any thing wrong with the code.

Whats the difference in the code from document A and B?

Answer 1

You’ve got an Zero-width space (U+8203) behind the closing bracket.

The bug is known to jsfiddle, it seems to be an issue with the codemirror syntax highlighter.
