Why a font has these four presentations?
1. It seems right
2. It is exasperating (rare characters display)
3. No can open (even though appear to be a font)
4. No can open (Do not even know if it's a font file)
I've looked at a lot of these different files, and I decided to ask exactly what they mean, 'I guess it's something like TTF or OTF format, but if someone could give me a more complete information would be excellent. Thanks for reading!
