Help with pixel fonts

Hello just a quick question.

When using pixel fonts, and when I embed characters… Do I need to embed those fonts every place where I used the font? In other words, say I have a bit of text that says “New Design Concepts”, in FFF Corporate… If I click the character button and embed the characters… Does it only embed the characters used in that text field? Or does it embed the entire character set (per checked)? And do I need to do this for each instance of pixel fonts in my site? Or just embedding it once will be fine for the entire site?

Sorry I’m really unclear about this.

Thanks for the help
