02.23.2006 - Unicode Lookup

Several folks have contacted me since publishing Alternatives to innerHTML asking how to create special characters with createTextNode.

If you were to use document.createTextNode("&"); you will literally get & written to the document rather than the ampersand you are looking for. The answer is to use the Unicode hex value for the character: document.createTextNode("\u0026");.

I wasn't able to turn up any reasonably useful charts of the codes, so to make this a bit easier I've thrown together a quick application that will do the lookup for you. Just type in the ASCII integer value or the character itself and it will present you with the Unicode hex value.

A good unicode page I found the other day... <a href="http://www.digitalmediaminute.com/reference/entity/index.php">http://www.digitalmediaminute.com/reference/entity/index.php</a>

Curses... foiled again. You need to put a note about HTML is not allowed in comments or something.

Here's a cleaner line to copy:

See, thats the sort of chart I would have *liked* google to have turned up for me. Oh well...

"No HMTL Allowed" added ;)

Just as a note, the backslash before u in the Unicode character escape doesn't show up in Bloglines. I'm not sure whether that's your RSS feed or Bloglines doing it.

For Mac users, Unicode Font Info [1] is a free tool which provides Unicode and HTML information and allows you to check out which glyphs are present in the fonts on your system. Very handy indeed.
