html2canvas not working with @font-face font in chrome

I am using http://html2canvas.hertzen.com/ for converting my html into
canvas. it is a great script.
it works very well with english font.. .but i am working with gujrati
font. i'm including font from css (@font-face)
it works well in firefox, but in chrome it does not show the exact character.
is there any options i missing in this code?
html2canvas(document.body, {
onrendered: function(canvas) {
document.body.appendChild(canvas);
},
width: 300,
height: 300
});
