Font symbols look not sharp

[AGavrashenko]

Hello. I'm using svg2ttf for generating ttf font for processing to other formats like eot, woff, etc. I've noticed that icons in ttf are have crashed edges in IE and Firefox(Windows).

Currently, I use this config:

{
    fontHeight: 1024,
    ascent: 896,
    descent: 128
}

But I've tried different variants and received the same result.

Also, I've tried to convert my svg font via other online tools. The result I received (svg2ttf from the left):

All screenshots was made in IE. As you can see, the font looks much better. So, is this an issue of svg2ttf?

Did you tried to apply ttfautohint after svg2ttf?

I guess, that's not issue of svg2ttf then.
