Notes

Most of these are used in Japanese, as Japanese printing frequently use the style of putting things into a square box.

Unicode does not necessarily specify the meaning of a glyph/char it provides, because, some glyph can mean multiple things. For example, (U+33B0: SQUARE PS) can mean “pico seconds”, or it can mean “postscript”.

Avoid using these. Because it's not a complete system for specifying units. For example, they don't cover all the metric system prefix.
