I'm an intermediate graphics designer by hobby, and I have a collection of a few hundred TrueType fonts. Over the years, I've noticed an ever-growing presence of OpenType fonts, and I've become curious.
So, the question is, what's the difference between TrueType and OpenType fonts, and what does it mean for me? If they're significantly more beneficial or universal, would I be safe in "upgrading"/replacing my TrueType fonts with their OpenType counterparts?
Thanks in advance.
