I didn't see special Unicode symbols for the SI units in the link you gave or in a more general search. I found no match for "ampere" which is the SI base unit for electric current, or for "candela", used for luminous intensity. BTW, just because a character exist doesn't mean it's the best choice for ordinary use. As https://en.wikipedia.org/wiki/%C3%85#Symbol_for_.C3.A5ngstr.C3.B6m https://en.wikipedia.org/wiki/%C3%85#Symbol_for_.C3.A5ngstr.... points out: > Unicode also has encoded U+212B Å ANGSTROM SIGN. However, that is canonically equivalent to the ordinary letter Å. The duplicate encoding at U+212B is due to round-trip mapping compatibility with an East-Asian character encoding, but is otherwise not to be used.
