x207B

x207B refers to the hexadecimal code point 0x207B in the Unicode standard. The character assigned to this code point is called SUPERSCRIPT MINUS, and it is located in the Superscripts and Subscripts block, which spans U+2070 to U+209F. This symbol is a small minus sign raised above the baseline and is used in contexts that require a superscript negative sign, such as certain mathematical notations and typographic conventions. It is distinct from the standard ASCII hyphen-minus (U+002D) and from the minus sign (U+2212).

In terms of encoding, the character is represented in Unicode as U+207B. Its UTF-8 encoding is the byte sequence E2 81 BB, while UTF-16 uses the code unit 0x207B and UTF-32 uses 0x0000207B. In HTML or other markup contexts, it can be referenced numerically as ⁻ or ₇.

Rendering of x207B depends on font support. Many modern fonts that include the Superscripts and Subscripts block provide a glyph for SUPERSCRIPT MINUS, though some fonts may render a visually similar, smaller version of the regular minus sign instead. As with other specialized Unicode symbols, its availability can vary across platforms and text environments.

Usage notes: SUPERSCRIPT MINUS is primarily used where a negative sign is intended to appear as a superscript, such as in certain mathematical formulas or specialized typography. For standard exponent notation, many systems rely on superscript formatting combined with a normal minus or with explicit exponent notation. In practice, when precise glyph shape is important, selecting a font known to support the SUPERSCRIPT MINUS is recommended.
