I've noticed some odd kerning for a few of the characters, the most obvious one being the capital "I" which has an extra pixel on its left side causing awkward gaps in some words. Image provided to show what I'm talking about.  There's also a similar issue with the exclamation mark and some other characters, but the "I" is the one that really stands out.

I am not sure, but I think there might not be any kerning at all (for any characters). Did you do some more tests or do you happen to know more about this?

I have no idea in terms of what sort of embedded kerning info is embedded in the font.  But the issue with the spacing around the letter "I" appears consistently in a variety of software, so there's something wrong going on with the font.
