Not The Roadmap
This page lists scripts which, for one or another reason, are not given tentative pre-allocations in the Roadmap tables for addition to ISO/IEC 10646 and the Unicode Standard. Several categories are provided, to indicate the reasons why a script might not be suitable for pre-allocation in the Roadmap tables. For known scripts for which there is enough information and sufficient reason to do some rough pre-allocation, see instead the Roadmap tables for the BMP, SMP, SIP, TIP, and SSP.
Known scripts which have been investigated, but which are unified with existing encoded scripts.
Scripts (or pseudoscripts) which have been investigated and rejected as unsuitable for encoding.
Known scripts, with enough information, but insufficient reason to provide pre-allocation.
Things rumored to be scripts, but not clearly enough attested for us to even determine whether they are "known scripts".
