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
[edit]As of 12 December 2017[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
[edit]The following IVS collections are currently registered in the IVD:[3]
| Region | Name | Purpose | First registered | Last updated | Number of sequences | Chart |
|---|---|---|---|---|---|---|
 Japan |
Adobe-Japan1 |
CID-keyed Japanese OpenType fonts. Defines at least one sequence for every Japanese kanji from the Adobe-Japan1 collection present in Unicode, even for those with only one glyph, both as future-proofing and to allow that (Japan-region) glyph to be uniquely referenced.[5] |
2007-12-14 | 2022-09-13 | 14684 | |
| Japan |
Hanyo-Denshi |
Unicode characters corresponding to more than one glyph collected by the Han'yō Denshi programme, a union of the character repertoires of the legacy kanji character sets used by multiple administrative systems in Japan (precursor to Moji Jōhō Kiban).[6] Approximately 60% of the initial registration matches Adobe-Japan1 glyphs, but the existing Adobe-Japan1 variation sequences are not used for them.[7] |
2010-11-14 | 2012-03-02 | 13045 | All Han'yō Denshi sequences |
| Japan |
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.[6] |
2014-05-16 | 2017-12-12 | 11384 | All Moji Jōhō sequences |
 Macau |
MSARG |
Macao Supplementary Character Set (MSCS) | 2016-08-15 | 2020-11-06 | 154 | All MSCS sequences |
 South Korea |
KRName |
Standard character variants permitted in personal names in South Korea | 2017-12-12 | 36 | All Korean name sequences | |
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.[8] In some cases, multiple of these correspond to a single Unicode character.[9] Many of these cases are currently handled with mappings to the Supplementary Private Use Area.[9] 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.[9][10]
