I do not have comment advantages, or I would certainly have left this as a talk about an earlier solution.

DO NOT, I duplicate, DO NOT run away an apostrophe in HTML making use of

'

This is not a legitimate HTML personality entity reference. It is an XML personality entity reference. While Firefox and also Chrome, at the very least, will certainly provide the above as an apostrophe in an HTML record, Internet Explorer will certainly not. And also it is adhering to the criterion when it rejects to do so.

You might run away an apostrophe in HTML making use of

'

But I do not think it is, as a whole, essential.

I do not concur with Nate. You need to preferably make use of as little running away as feasible and also make use of UTF - 8 to share personalities natively. To do this you require an editor that can take care of UTF - 8 along with a proper charset declaration, such as :

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

However, you need to make it a behavior to run away the personalities that have an unique definition in (X) HTML, particularly :

< &lt;
> &gt;
" &quot;
& &amp;
' &#39;

This will certainly see to it you are not mistakenly creating markup when you intend to write these personalities. This is specifically vital for customer input, to keep security. It is much less noticeable, yet it is in fact vital to run away ". If a string ever before winds up in a HTML feature (title="something" etc) the customer can end the feature and also insert their very own markup. Visualize what takes place if the customer gets in " onclick="alert('hello'); and also you insert that to title="..."

If you are making use of PHP, you can make use of the htmlspecialchars function to do this. Various other languages might have various other comparable features.

Update : I stand dealt with on the apos concern. Damned pesky IE.
