- How come? I can use the base letter A for indexing, it can not be used to
- identify the actual letter (which may have one or more diacritics floating
- around). (Sorry you nordic people that I make a diacritic from the ring!)

- As I understand it each character has only one radical. (I learned that
- a character consists of a radical plus possibly additional strokes.) You
- have the misunderstanding that a character is composed of a number of
- radicals. (BTW, this is true of the Korean Hangul, but that is actually
- an alphabetic script, each base symbol represents a sound.)

- Unique in the sense that they do not contain radicals.
