It looks like an interesting implementation, but it uses Alchemy. I've been reading up more on Alchemy, and according to Adobe it's pre-release, and they advise that it "not be used to generate code for use in production". In any case, the Alchemy APIs make passing arbitrary data to/from the FFT a bit clunky, e.g. passing a Vector of Numbers requires conversion to a ByteArray first. For what it's worth, I've posted my pure-AS3 FFT implementation here: http://gerrybeauregard.wordpress.com/ ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

SOLVED: RE: [Flashcoders] % glyph not displaying
Hi Jason! Thanks for responding, just this moment, I figured it out: The % sign needed to be URL encoded for it to be properly passed through via the flashvars. http://www.kirupa.com/forum/showthread.php?t=328548 - Michael M. > How exactly did you embed the font in the .swf and what glyph sets did you select when you did?

Re: [Flashcoders] % glyph not displaying
Try explicitly adding the "%" to the "Include these characters" field.

[Flashcoders] % glyph not displaying
Hi list... I've embedded Times New Roman in a swf and I'm populating a TextField via flashvars set in that embedded Times font. The % glyph isn't displaying. No matter what type of entity I include in the flashvar string (\u0025 or &37; or %), the percent sign isn't showing up. In Windows Character Map, the % sign is obviously part of the character set.

How exactly did you embed the font in the .swf and what glyph sets did you select when you did?
