The ancient Egyptian Shuti, a two-feather adornment for crowns, is part of a series of hieroglyphs for "crowns"; usage as a hieroglyph is not as common as the actual crown represented in Egyptian art, and artworks.
It is shown in iconography in both the straight-feather form (when used as a doubled crown).
The Budge two-volume dictionary of hieroglyphs records 20 spellings for shuti, from multiple sources.
[1] Besides the single hieroglyph, nine spellings use the shuti as a determinative.
Maat as a representative of truth, wisdom, justice, order, etc., in the kingdom, the iconographic headdress implies her role, to the one who wears the shuti two-feather adornments.
