U+2103 "℃" Degree Celsius Unicode Character
U+2103 "℃" Degree Celsius is a precomposed typographic symbol that represents the degree Celsius unit of temperature, which is named after the Swedish astronomer Anders Celsius. It is distinct from the common practice of typing the letter "C" after a degree sign (°) as a separate character, instead combining both elements into a single glyph for convenience and consistency in digital text. This character is part of the Letterlike Symbols block in Unicode and is primarily used in scientific, meteorological, and everyday contexts to denote temperature measurements in the metric system. Its inclusion in Unicode ensures standardized rendering across different platforms and fonts, avoiding potential spacing or formatting issues that can arise from composing the symbol manually.
