In '''[[Unicode]]''' a '''block''' is defined as one continuous range of code points. Blocks are named uniquely and have no overlap. TheThey may be defined with the starting and ending code points. The block explicitly can include code points that are unassigned and non-characters.<ref>[http://www.unicode.org/glossary/#B Unicode glossary]</ref> 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".

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, although a block name will have a descriptive nature: "Tibetan" or "Supplemental Arrows-A". All assigned code points have a single block name.
