Hangzhou Misnomer
In the Unicode standard version 3.0, these characters are incorrectly named Hangzhou style numerals. In the Unicode standard 4.0, an erratum was added which stated:
The Suzhou numerals (Chinese su1zhou1ma3zi) are special numeric forms used by traders to display the prices of goods. The use of "HANGZHOU" in the names is a misnomer.
All references to "Hangzhou" in the Unicode standard have been corrected to "Suzhou" except for the character names themselves, which cannot be changed once assigned, according to the Unicode Stability Policy. (This policy allows software to use the names as unique identifiers.)
In the episode "The Blind Banker" of the 2010 BBC TV series Sherlock, Sherlock Holmes refers to the numbers as "Hangzhou" instead of the correct one "Suzhou."
