Generates corrupted svg files.

[roelvanhintum]

Using the gulp-iconfont in combination with gulp-iconfont-css and standard configuration outputs corrupted svg files. I'm guessing this also corrupts the eot ttf and woff files.

The only config i used was fontName.

I see a lot of the following in the svg file (NaN and undefined):

<font id="icons" horiz-adv-x="NaN">
    <font-face font-family="icons"
      units-per-em="NaN" ascent="NaN"
      descent="0" />
    <missing-glyph horiz-adv-x="0" />
    <glyph glyph-name="arrow-down"
      unicode="&#xE001;"
      horiz-adv-x="undefined"

Wierd indeed. Can you give me the input icons ?

I tested it with just this one and it still occurs.

It looks like the problem comes when the width and height attributes of the SVG icon is not mentionned.

I think using the viewport attribute will solve the problem http://www.w3.org/TR/SVG/coords.html#ViewBoxAttribute .

I don't know which editor you use, but using Inkscape will ensure you have a width and a height during the time i fix this up.

A simple fix:
nfroidure/svgicons2svgfont@0ce026b
nfroidure/svgicons2svgfont@26fd049

A better fix would be nfroidure/svgicons2svgfont#9

I will ship when i'll have enought feedback for this issue nfroidure/svgicons2svgfont#7

The svg's are coming from Illustrator, looks like i messed up the export settings.

The responsive svg option seems to be the problem here.

Could you PR the README with a section explaining wich AI options are the best ?
