Current Allocation

The following tables give the statistics for currently unassigned (reserved) code points in the Basic Multilingual Plane (BMP) and in the Supplementary Multilingual Plane (SMP) for Unicode 6.3.0.

First, a few definitions.

A set of 16 Unicode code points that all have the same "div 16" value, e.g. U+2040..U+204F or U+1D120..U+1D12F. (The name comes from the fact that they occupy a vertical column in the character charts.)
empty column
A column where none of the code points are designated.
partial column
A column where some code points are designated and some are reserved.

For practical reasons, the Unicode Technical Committee avoids splitting character blocks across columns. For that reason, it is important in new allocation to distinguish code points from these sources:

  • reserved code points not in blocks
  • reserved code points in empty columns (within assigned blocks)
  • reserved code points in partially allocated columns (within assigned blocks)
  • designated code points (includes assigned characters, private use, surrogate code points, and noncharacters—all of which are unavailable for assigning new characters) 

Here is the breakdown in Unicode 6.3.0:


  Reserved Designated
  Not in Blocks in Empty Columns in Partial Columns

Code Points












  Reserved Designated
  Not in Blocks in Empty Columns in Partial Columns

Code Points










The following lists the reserved code points in empty columns in more detail. It is separated into two parts: 1. empty columns in unassigned ranges (or areas), and 2. empty columns in assigned blocks. The numbers in the second column represent the number of reserved code points in each range.
