A block in Unicode is a named, single continuous group of code points, e.g. Miscellaneous Symbols Unicode block with range U+2600–26FF. Each character is in one block. A block can include non/assigned code points, non/character codepoints etcetera.
A script is related to speech (like the alphabet), symbols are related to their meaning (like chess-symbols). Symbols also include controls and Unicode-specials like Byte 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 from pairs of characters with an overlapping meaning etc.
Special characters have a Unicode-defined behavior.
Miscellaneous lists are lists of characters that are not in one block. Cultural symbols like religious crosses are in different blocks.
