Celsius and various publishing houses, may follow different typographical rules. Unicode provides the Celsius symbol at code point . However, this is a compatibility character provided for roundtrip compatibility with legacy encodings. It easily allows correct rendering for vertically written East Asian scripts, such as Chinese. The Unicode standard explicitly discourages the use of this character: "In normal use, it is better to represent degrees Celsius "°C" with a sequence of + , rather than . For searching, treat these two sequences as identical." Shown below is the degree Celsius character followed immediately by the two-component version: When viewed on computers
