The Importance of Character Encodings

I'm amazed at how many non-supported characters I see out on the Web. I spent a long time researching and deciphering just how to use the proper character encoding so that this doesn't happen to you. You can read all about it in Chapter 21, Symbols and Non-English Characters, of my HTML, XHTML, and CSS: Visual QuickStart Book.

Doing some research on Barnes and Noble's new electronic book reader, the nook, I saw this:


Looking at the source code, you can see that B&N did not declare their character encoding. Firefox assumed it was UTF-8, but since it wasn't, the special symbols display incorrectly. If you're just a Web site visitor and want to see the page without those annoying question marks, go to View > Character Encoding, and choose a different encoding from the one Firefox tried originally. If that happens to match the character encoding that the Web site creator used, you're in luck. If not, try again until you find it.

If you're a Web site designer, be sure and declare your page's Character Set so that browsers don't have to guess. At the top of your page, put:

<meta http-equiv="content-type" content="text/html;charset=code" />

where code is the character set encoding you used to write your page. I explain how to tell which one you used (and how to choose an appropriate one if you're not already), in my book!

Copying a file with Command-C

OK, before I tell you what I just discovered, I feel compelled to note that I have been using a Macintosh since 1985!

I was watching a video tutorial this morning and the guy copied a file on the desktop by pressing Command-C and then switched to another folder and pasted it in there by pressing Command-V. Did you all know you could do that? I sure didn't. Not sure if it's useful, but it definitely took me by surprise, even though it's completely logical and obvious.

Thought you should know too!
