IE11 displays line breaks as missing gylph (�)
I minified a font with fontmin. I used [this demo repro](https://github.com/junmer/gulp-fontmin-demo).

The Demo can be found here:

Internet Explorer 11 thinks, there is no SPACE character in the font, so it displays a missing glyph character at every line break (`<br />`):
