On Windows ALT+248 (on keypad) makes a degree symbol: ° IMO it looks better than the single glyph. (°C °F vs ℃ ℉)

  Unicode agrees: > Several letterlike symbols are used to indicate units. In most cases, however, such as for SI units (Système International), the use of regular letters or other symbols is preferred. > In normal use, it is better to represent degrees Celsius “°C” with a sequence of U+00B0 degree sign + U+0043 latin capital letter c, rather than U+2103 degree celsius. For searching, treat these two sequences as identical. Similarly, the sequence U+00B0 degree sign + U+0046 latin capital letter f is preferred over U+2109 degree fahrenheit, and those two sequences should be treated as identical for searching.

    The why include the symbols in the first place? Just in case?

      So we can make search that tiny bit more complicated.

      For lossless round-tripping with legacy character sets. This is one explicit design goal of Unicode.

      It's most likely for round-trip compatibility with another encoding. There are many Unicode codepoints that simply represent combinations of other codepoints. If you don't care about round-tripping, just normalize everything to NFKC or NFKD (the difference being that accented letters like á are one codepoint in NFKC and two codepoints for the base letter and combining mark in NFKD).
