How to Code Double Quotes via HTML Codes

Question

In HTML, What is the preferred way to specify html codes like ", and what is the major differences? For example:

&quot;    <!-- friendly code -->
&#34;     <!-- numerical code -->
&#x22;    <!-- hex code -->

Which one should I use and would it ever be an issue if one of these gets deprecated?

Answer 1

There really aren't any differences.

" is processed as " which is the decimal equivalent of &x22; which is the ISO 8859-1 equivalent of ".

The only reason you may be against using " is because it was mistakenly omitted from the HTML 3.2 specification.

Otherwise it all boils down to personal preference.
