Hello & thanks for the great theme.
I seem to be having a problem uploading webfonts if they have more than one word in the title: for example, uploading 'Roboto' works fine, but if I want to upload 'Roboto Mono' I get an error message saying: "Only letters numbers and underscores allowed ..."
This seems odd - after all, Times New Roman has several spaces in the font name....
if i take out the spaces in the name (ie. RobotoMono) or use an underscore instead of a space, the font doesn't work on the site.
