Why would anyone build with this?

REASON 1

Scan a full character set to find glyphs that visually touch or overlap.

REASON 2

Catch collisions between accented letters, numerals, and punctuation you might miss manually.

REASON 3

Export the collision list as a text file to feed into Metrics Machine for kerning work.

REASON 4

Run checks on a smaller subset of glyphs to get faster feedback during design.
