Correct spelling mistake.

Very simple fix of typo in fonts.md.

It's "Non-existent" not "Non-existant".

"Nonexistent" (no hyphen) is also the most common current usage so switched to that form.

Google says 10.3m results for "nonexistent" and 20m for "non-existent", so I'm not sure that the non-hyphenated version really is more common

Maybe "common" isn't the right word. It is the nature of hyphens to atrophy and die as a formulation becomes more common. (See e-mail versus email.) For me the worm has turned on nonexistent so I prefer to go with what I see as a near-inevitable (not nearinevitable!) future. Merriam-Webster has it without a hyphen.

All that said the Times of London is still using the hyphen (at least in 2016) and I am 100% happy to return the hyphen if you prefer. I mostly just wanted to correct the spelling (it's "non-existant" in the source right now not "non-existent"). So if you prefer the hyphen I can return it. LMK.

I personally would prefer Non-Existent. Partially because I don't see the need to change something that's fine now, but mostly because it's just the way I'm used to seeing it. In any case I know I'm being a bit nit picky :-)

Thank you for fixing the typo!!

I'm fine with both, though, translation tools I use return Nonexistent (WR, Linguee). If that makes debate, we could also change the title for Missing Fonts which is IMO more straightforward to understand for non native English.

The Gordian Knot is cut! "Missing Fonts" pushed. Thanks!
