I’ve seen this about on templates for a while, I tried to do some research but I still don’t completely understand it. From the one hand I thought it was a font and from the other hand I read somewhere it’s a JavaScript rendering script to allow crisper fonts. I thought wants were crisp. puzzled
I’ve read the webpage, it helped a lot. I’ve never used cufon font replacement. I use typekit for my non-standard fonts. I think I might have missed the train and there is no longer a need for me to know about cufon font replacement.
Yes, I’ve never actually used cufon and the fact that you can’t copy and paste text with it makes it only useful for small headings etc. @font-face is a better option these days if non standard fonts are required.
