The Unicode pipeline is always full of new characters, scripts, character properties and algorithms. See also Unicode Technical Report for drafts and proposed drafts of upcoming changes.

Many scripts have had a range of character codes tentatively pre-allocated for them, but remember that anything might change, if it is not yet part of a released version of the standard.

Here is the tentative future, as of December 2007.


Scripts which have been formally accepted by UTC or WG2 for processing toward inclusion in the standard. Many of these will be part of Unicode 5.1.

Not Pre-allocated

These scripts, for one or another reason, are not given tentative pre-allocations. Several categories are provided, to indicate the reasons why a script might not be suitable for pre-allocation.

Known scripts which have been investigated, but which are unified with existing encoded scripts.

Scripts which have been investigated and rejected as unsuitable for encoding. Known scripts, with enough information, but insufficient reason to provide pre-allocation. Known scripts, but insufficient information to do a decent job of rough pre-allocation, and/or insufficient to know whether a pre-allocation is warranted. Things rumored to be scripts, but not clearly enough attested for us to even determine whether they are "known scripts".
