position of icon changes when I combine two font-files

[t...@mms-dresden.de]

Hi,

to let the browser download two different font-files in parallel, I'm trying to combine them with the use of "unicode-range" at the @font-face declarations in the css file.

Chrome perfectly downloads both files in parallel and displays the icomoon-icons and the custom ones at the correct position (centered).

Firefox displays the icomoon-icons at the top instead of centered.

If I revert the order of the @font-face declarations to have the custom-build icons at first, all browsers display all the icons centered but the effect of parallel download is gone.

I know, I could combine both font-files into one, but for now I am searching for another solution.

Anyone have an idea, what's causing this?

Thanks.
