X height: 1 and a half brick. Exist a second U in the "u" glyph.
The name "zashitnik" comes from the great "Luna" sci-fi trilogy by Ian McDonald (meaning fighter with knives hired for trials by combat, literally "defender").
Work in progress (kerning and more glyphs to come).
There is also an alternate "s" in the "™" glyph, and the "ff" and "tt" ligatures placed on "fi", "ff" and "fl" respectively.
