In '''[[Unicode]]''' a '''block''' is defined as one continuous range of code points. (numbers)Blocks are named uniquely and have no overlap. The block may be defined with the starting and ending code points, and is named. The block explicitly can include code points that are unassigned and non-characters.<ref>[http://www.unicode.org/glossary/#B Unicode glossary]</ref> Every assigned code point has a property "Block name", which describes to which block the character belongs. Code points that are not in one of the named blocks, e.g. in the unassigned [[Plane (Unicode)|planes]] 3-13, have the value block="No_block". All assigned code points have a block name.

Conversely, every assigned code point has a property "Block name", which names in which block the character is. This is determined by the code point only, all though a block name will have a descriptive nature: "Tibetan" or "Supplemental Arrows-A". All assigned code points have a single block name.

Subdivisions, such as "[[Chess Symbols]]" in the block [[Miscellaneous symbols (Unicode block)|Miscellaneous symbols]], are not a "block". A subgroup name is an informative editorial addition to the charts only.
