Named HTML entities in numeric order

Below are the entities listed in numeric order with definition and ISO numeric code. CSS 'content' does not accept named entities or regular numeric entities such as @, but does render ASCII text and unicode.

If you want to replace the bullets in a bulleted list with a different character, perhaps a ♥ or · you would need to use the unicode entity rather than the named or numeric entity: use the hexadecimal entity.

li:before {content:"\2665"; text-indent: -10px;}

JavaScript Special Characters / Entities

If you want to include characters in JavaScript, the process is very similar to the CSS inclusion method, except : in JavaScript use octal-encoded characters without a preceding 0 instead of the HTML entity for the normal chars, and the hex character preceded by a \u for all other characters..

alert('M\351nage \340 trois.')

Notes:

If you know the numeric value of your HTML entity, use the handy CSS & Javascript Entity Calculator to get the JS and/or CSS code
There is a much smaller list of named entities in alphabetical order which may be a good place to start. Find the entity you are looking for there by appearance, then do a search for the numeric entity or named entity here.
Remember that IE doesn’t understand the :before pseudoclass with content, and you would have to set the list-style-type as none, or you would get 2 bullets in CSS compliant browsers.
In the above if you see two backslashes it’s because some browsers escape the backslashes and others don’t, so I stuck two in.
If you click on any javascript entities in the "alerts" javascript entity column below, the entity will show up as an alert.
