Ascript is related tospeech (like the alphabet),symbols are related to theirmeaning (like chess-symbols). Symbols also include controls and Unicode-specials likeByte order mark(BOM). All defined Unicode characters are either in a script or a symbol.
Charts are examples of glyphs, i.e. a rendered character (the "A" you read)
Due to legacy character sets like ASCII, and due to intended usage of Unicode, multiple issues arise frompairs of characters with an overlapping meaning etc.
Special characters have a Unicode-defined behavior.
Miscellaneous lists are lists of characters that arenot in one block. Cultural symbols like religious crosses are in different blocks.
