Windows Chrome appears to be ignoring the kerning tables in the True Type files, as 'fox' appears fine (for me) on everything else I'm testing on. If I've missed something please let me know.
Chrome doesn't shape text (ignoring kerning) if it contains entirely Latin text, as a questionable performance optimization that really reduces legibility of text (IMO). You can use "text-rendering: optimizeLegibility;" to force it to obey kerning.
That's because the kerning tables in this font are woefully incomplete. The only pairs defined are "//", "Ke", "To", "We", "Ze", "Zo", "iz", "oz", "yp", "'r", and "'s".
Then again, Comic Sans from MS has no kerning at all.
The "fo" pair looks decent, but many others leave a lot to be desired. I don't have an explanation for the differences though. Maybe Libreoffice is using a different layout engine.
