Variation Selectors Supplement is a Unicode block containing additional variation selectors beyond those found in the Variation Selectors block.
These combining characters are named variation selector-17 (for U+E0100) through to variation selector-256 (U+E01EF), abbreviated VS17 – VS256.
Ideographic Variation Sequences
As of 23 October 2025[update], VS17 (U+E0100) to VS48 (U+E011F) are used in ideographic variation sequences in the Unicode Ideographic Variation Database (IVD).[3][4] These selectors are known as Ideographic Variation Selectors (IVS). They are not listed in the list of standardized variation sequence, instead they are listed in another Ideographic Variation Database.[3]
IVD collections
The following IVS collections are currently registered in the IVD:[3]
| Region | Name | Purpose | First registered | Last updated | Number of sequences | Chart |
|---|---|---|---|---|---|---|
Moji_Joho |
Unicode characters corresponding to more than one entry in the Moji Jōhō Kiban, a database of kanji used for administrative purposes in Japan. Supersedes and deprecates the Hanyo-Denshi collection, from which it retains 9866 of the existing IVSes.[5] |
2014-05-16 | 2017-12-12 | 11384 | All Moji Jōhō sequences | |
MSARG |
Macao Supplementary Character Set (MSCS) | 2016-08-15 | 2020-11-06 | 154 | All MSCS sequences | |
KRName |
Standard character variants permitted in personal names in South Korea | 2017-12-12 | 36 | All Korean name sequences | ||
CAAPH |
Variant forms required for digitization of intangible cultural heritage in databases and e-books by the Culture and Art Publishing House.[6] | 2025-07-14 | 198 | All CAAPH sequences | ||
Proposed IVD collections
As of 23 October 2025[update], there are no IVD collection submissions under review.[3]
Similarly to the Moji Jōhō Kiban's role in Japan, the character repertoire of CNS 11643 (including draft revisions) is used for administrative purposes in Taiwan.[7] In some cases, multiple of these correspond to a single Unicode character.[8] Many of these cases are currently handled with mappings to the Supplementary Private Use Area.[8] However, the Taipei Computer Association, which represents the interests of Taiwan in the Ideographic Research Group, has been evaluating the feasibility of registering an additional IVD collection in the future.[8][9]
