05 FAQ
What is the Unicode code point for the account of sign?
It is U+2100, decimal 8448. There is no Windows Alt code for it.
Is it still used?
Very rarely. It survives in older ledgers and printed forms. Modern accounting writes a/c or spells out the word.
Why does Unicode include it?
It was present in earlier character sets used by typewriters and business machines, so Unicode encoded it to allow lossless conversion of that material.
How is it different from ℅?
Account of at U+2100 is a bookkeeping abbreviation. Care of at U+2105 is an addressing one. They are built from different letters and mean unrelated things.
Why does it show as a box?
Few fonts include this character. If the box appears, write a/c in plain letters, which is what readers expect anyway.
