Unicode® 18.0 Delta Charts Index

New blocks are highlighted in yellow in the Character Additions table. Blocks which also have significant glyph updates, as well as the character additions, are starred. The "New Characters" column gives the number of new characters encoded in Unicode, Version 18.0 for previously existing blocks, or the total number of characters for new blocks.

Blocks containing no new characters, but with significant glyph updates, significant metadata updates (for CJK ideographs), changes to standardized variation sequences, or new formal name aliases are highlighted in blue in the Glyph, Variation Sequence, and Name Alias Changes table. That table lists specific characters or ranges of characters with glyph updates in the "Code Points" column. This convention makes it easier to find the relevant glyph changes in very large CJK ideograph code charts.

For more information about these charts, please see Character Code Charts Help and Links. These charts are referred to as delta charts, because they document the "delta", or changes, between this version of the code charts and the code charts of the prior version. A full set of all code charts for this version is located at Unicode 18.0 Code Charts
