Unicode symbols
For the purposes of compatibility with Chinese, Japanese and Korean (CJK) characters, Unicode has symbols for:
- millimetre (㎜) - code 339C
- square millimetre (㎟) - code 339F
- cubic millimetre (㎣) - code 33A3
They are useful only with East Asian fixed-width CJK fonts, because they are equal in size to one Chinese character.
