Do you know that all letters in Iosevka are EXACTLY 1/2 em wide?

For ASIAN users, you can use THIS and preserve your perfect alignment.

So the "m" glyph is half as wide as itself?

The em unit is traditionally the width of the letter M, but these days you see it used as the unit height of a font. IIRC, CSS is like this.
