I really like the script but the example is not working for me in IE. 

'undefined' is null or not an object
typeface-0.14.js  Line:601
Code: 0                Char: 5

Need help....

Hello, this looks like a bug that happens when the font file doesn't contain one of the characters you want to display. 
Try to change the line 597 with:

      this.renderGlyph(shape, face, this.fallbackCharacter, offsetX, style, vmlSegments);

did this work for you?

doesnt for me...

This is an error caused from letters trying to be displayed but the character set not being included in the converted font.

I had a   in my letters...I removed that char, and everything worked!
