In Unicode, a code block is a named set of contiguous character assignments. Every assigned character is in exactly one code block. Code blocks have an even multiple of 16 code points reserved, some of which may not be assigned.

In future versions of the standard, new code blocks may be defined in the current gaps, and unassigned code points within code blocks may be assigned, but nothing else should change.

The columns in the table below should be interpreted as

  1. The range of code points reserved for this code block
  2. The name of the code block
  3. The total number of code points assigned over the number reserved.
  4. The version, or range of versions, in which characters were assigned to this code block, and the number of characters assigned in that version.
Up to date as of Unicode 5.2.
