Font loading error: downloadable font: kern: too large subtable, the table is discarded

Question

I try to use the "Open sans" font on my web page, and only in Firefox do I get this error in the console:

downloadable font: kern: subtable too large, table dropped

Here is the CSS:

@font-face { font-family: Open Sans; src: url(OpenSans-Semibold.ttf); } 

Answer 1

I was looking a bit, and the problem seems to be related to a subset of Open Sans.

This user ( fooobar.com/questions/574236 / ... ) seems to have encountered a problem downloading a font from Google Fonts. Try downloading it from Font Squirrel and see if it fixes it.
