Kiri font has broken 0 (zero) character.

Width of zero character is incorrect in kiri font.
This cause overlaping other characters on zero character.
It is quite easy to fix in FontForge.

Thank you for reporting. Have you done the fix yourself?

I edited KiriFont.otf and it works fine for me.
I'm not sure if it's complete solution.
