Pikto: U+000F0E70 - U+000F16A4
Pikto consists of a vocabulary of 2100 'Master Words' taken from English, German, French and Russian. The words are supposed to cover the entirety of human experience in broad strokes, and can be chained together to give more precision. Each 'Master Word' also has its own hieroglyphic; these are each given a surrogate-space Unicode codepoint in the range 000F0E70-000F16A4. Algorithmic names of the form PIKTO IDEOGRAPH-xxxx are used, where xxxx is a hex number from 0E70 to 16A4.
