Variation Selectors Supplement
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 through to variation selector-256, abbreviated VS17 – VS256.
Ideographic Variation Sequences
, VS17 to VS48 are used in ideographic variation sequences in the Unicode Ideographic Variation Database. These selectors are known as Ideographic Variation Selectors. They are not listed in the list of standardized variation sequence, instead they are listed in another Ideographic Variation Database.IVD collections
The following IVS collections are currently registered in the IVD:Proposed IVD collections
, there are no IVD collection submissions under review.Similarly to the Moji Jōhō Kiban's role in Japan, the character repertoire of CNS 11643 is used for administrative purposes in Taiwan. In some cases, multiple of these correspond to a single Unicode character. Many of these cases are currently handled with mappings to the Supplementary Private Use Area. 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.
