Presentation conventions
-
Bold text
indicates an allocated (that is, published) character collection.
There is a link to the charts on the Unicode web site.
-
(Bold text between parentheses)
indicates scripts which have been formally accepted by UTC or WG2
for processing toward inclusion in the standard. There is
generally a link to a mature proposal for the script.
-
(Text between parentheses)
indicates scripts for which proposals have been formally submitted
to the UTC or to WG2. There is generally a link to the formal
proposal.
-
?Text between question marks?
indicates scripts for which detailed proposals have not yet been
written. There may be a link to an exploratory code table.
-
??? in a block indicates that no
suggestion has been made regarding the block allocation.
NOTE: When scripts are actually proposed to the UTC or to WG2,
the practice is to "front" them in the zones to which they are
tentatively allocated, and to adjust the block size with regard to
the allocation proposed.
The size and location of the unallocated script blocks are merely
proposals based on the current state of planning. The size and
location of a script may change during final allocation of the
script.
