@font-face legality issues

I've just heard of the @font-face CSS attribute, an开发者_开发问答d I was wondering if there any legality issues.

I have heard that only certain fonts can be embedded? What about completely custom ones, like a Super Mario Bros. font? Is that legal to embed?

Just wondering..

Yes, as long as you are legally allowed in the font license to either redistibute the font and/or only redestribute in the usage of @font-face. IANAL and this is not legal advice.

Make sure the license mentions that web-embedding is allowed. SIL OPEN Fonts are web-embeddable.
