Section 33. VSes: 128 User-Defined Variation Selectors [#495]

Brief discussion of document L2/24-148 (= WG2/N5266).

[180-N6] Note: The UTC notes that, under existing stability policies and commitments, it cannot entertain proposals to add PUA code points to the standard, nor to set aside sections of the PUA reserved for specific functions such as more variation selectors. Proposals to encode additional variants using variation selectors should be constrained to use the existing architecture of variation sequences. Note that while VS17-VS256 are required for the definition of ideographic variation sequences (IVS), they are not prevented from sanctioned use in defining other variation sequences using non-ideographic base characters. [Ref. document L2/24-166 section 33 “VSes: 128 User-Defined Variation Selectors”.]
