latin: nyctographic alphabet by caroll

Square alphabet created by Lewis Carroll ~1891: left top corner is always
marked, other corners are either connected, dotted, or skipped; encoded
numerically and drawn as svg path.

Allows for 34 possibilities with top left anchor:
	  2^³        (3 dots, only used for A,U,V)
	+ 2^²⋅4 − 2² (2 dots with 1 line, 3 unused)
	+ 2^¹⋅4 − 2⁰ (1 dot with 2 lines)
	+ 2^⁰⋅4      (3 lines)
	+ 2⁻¹⋅4      (2 parallel lines)
	+ 2⁻²⋅4      (square)
