Instead of

>


I would like to use

►


but I don't know if it is a safe character? It does display on my FF, IE, Opera, and Chrome, but will it display fine all around the world?

Any assistance/explanation will be much appreciated.

Hi there Marvin_Hlavac,

It does display on my FF, IE, Opera, and Chrome, but will it display fine all around the world?

By the same token, how are you so certain that > will display fine all around the world? ;)

&gt is on my keyboard, and also many sites use &gt, so I'm assuming there is no issue.

Are you saying I'm OK to use ►?

Hi there Marvin_Hlavac,

Are you saying I'm OK to use ►?

Well, you have tested it in four of the most popular worldwide browsers. ;)

I just noticed Google.com uses ▼ which is a character identical in shape to the ► only it is rotated 90 degrees. So I guess I'm safe to use the ►.

Thanks.

It all depends on what encoding your server and pages are saying the content is encoded in.
If you use unicode characters, make absolutely sure your pages tell the browser the page is encoded in UTF-8 (or UTF16, in the unlikely event you should opt for that).

If your pages state they are encoded in e.g. ISO-LATIN-1 or so, that that character is a liability and likely to blow up soon rather than late.

If you let browser guess what encoding to use it's even worse: you cannot predict it anymore and the order of what they encounter becomes important and the like.

Aside of that, if you type it or use a htmlencoding to represent it isn't relevant anymore for a modern browser.

Bottom line go for it. But DO make 100% sure your html is sent clearly indicating it is encoded in UTF-8, or it'll not be safe.

swa66, I much appreciate your explanation. I don't know much about these things, but looking through the source code of my pages I've found the following:

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />

Is this good or bad?
