U+1D691 "𝚑" Mathematical Monospace Small H Unicode Character

Unicode Version 17.0

𝚑

U+1D691 "𝚑" Mathematical Monospace Small H is a typographic glyph that represents a lowercase letter "h" in a fixed width or typewriter style, specifically designated for use in mathematical and scientific notation where a monospace font is required to distinguish it from standard text. It belongs to the Mathematical Alphanumeric Symbols block, which provides a range of styled letters and digits to be used consistently in equations, programming contexts, or formal documents without relying on ordinary formatting. This character is distinct from the regular lowercase "h" in that its inclusion in the Unicode standard ensures it retains its monospace appearance across any compliant system, making it useful for representing variables, constants, or code fragments where visual uniformity is essential.
