Just a few more minutes of your time...
I will be dividing my SignWriting proposal into 2 parts. First,
encoding the symbols of the ISWA 2010. Second, a technical note
describing a lightweight SignWriting Cartesian Markup that can be used
with the symbols for script layout.
My proposal for encoding the symbols will require 674 code points.
* 652 for the BaseSymbols
* 6 for the fill modifiers
* 16 for the rotation modifiers
The SignWriting symbol set defines 37,812 valid symbols. Each of these
symbols can be defined with 3 characters: BaseSymbol, fill modifier, and
There are potentially 62,592 character combinations, but not all are
valid. Each BaseSymbol has a list of valid fills and valid rotations.
A few examples...
BaseSymbol 77 (U+1D852) , can be viewed by itself. A different glyph is
displayed when followed by fill modifier 3 (U+1DA94) and rotation
modifier 1 (U+1DA98) .
BaseSymbol 136 (U+1D88D) , can be viewed by itself. A different glyph
is displayed when followed by fill modifier 1 (U+1DA92) and rotation
modifier 2 (U+1DA99) .
All of the symbols are documented in the ISWA 2010 HTML Reference. This
reference will be updated as part of the proposal:
It will be proposed that initially fonts have restrictions for size and
shape. This restriction should be lifted if a scheme can be created
that eliminates the requirement of exact symbol placement for proper
Would such a proposal be close enough to the Unicode standard?
Thanks for your time,
