DEGREE CELSIUS

About this character

U+2103 is the single-character degree Celsius symbol, encoding the combined unit for Celsius temperature as one glyph. It is primarily used in meteorological reports, scientific writing, and everyday temperature references. The scale traces to Anders Celsius’s 1742 proposal, later inverted into the modern system. In typography and design, this codepoint offers a visually consistent alternative to typing “°C” as two characters, though font support varies. In programming and data processing, it appears as a Unicode literal in strings, but plain-text systems often prefer the two-character sequence to ensure compatibility across encodings and fonts.
