Hi Claudia,<br>
<br>
This is the Unicode 8 design approved by the UTC (Unicode Technical
Committee) in 2015. It was based on my work, but they made changes
I opposed. As it stands, the Unicode 8 design is incomplete,
flawed, and fictional.<br>

<br>
Discussions with the UTC are ongoing. In October 2017, the UTC
created an action item to respond to my issues, but I'm still
waiting for the response.<br>

<div>When you add a modifier "R2-3-4-...-16" to an
HANDSHAPE it will change the hand and the angle.... when
you add a modifier "F2-3-4-5-6" it will modify the side
of the hand you will see... And for the moment no
problem! For each hanshape you have 96 possibilities.<br>

That's the basic idea. Rotation modifiers R1 thru R8 rotate
counter-clockwise by 45 degrees. R9 thru R16 mirror the hand and
then rotate clockwise by 45 degrees. Fill modifiers F1 thru F6 deal
with palm facings. F1 thru F3 for the front perspective and F4 thru
F6 for the top perspective.<br>

<br>
For the handshapes, there are five exceptions that deal with the
heel of hand. These exceptions use R1 thru R16, but only F2.<br>

This is not exactly right and the movement symbols demonstrate that
the fill modifiers and rotation modifiers are really nothing more
than column and row.<br>

<br>
The ISWA 2010 contains 652 base symbols. For each of these base
symbols, Valerie created a grid of symbols with 6 columns and 16
rows. There are many general rules, but none are universal.<br>
<br>
Generally speaking, for movement, F1 is for right hand, F2 is for
left hand, and F3 is for both hands when the movement overlaps.
Sometimes F4 contains arrow stems without the arrow head.<br>
<br>
<img src="cid:part2.E0EDEB32.F9B78621@signpuddle.net" alt=""><br>
<br>
<br>
Other times, F4 is for alternate right, F5 for alternate left, and
F6 for alternate overlapping movement.<br>

<div> HERE IS MY QUESTION... for this modification you just
need no-F (F1), F2 and F3... you dont need F4, F5 and F6
because for every movement you just have 48
possibilities...<br>
</div>
<div>1) what happen if I use F4, F5 and F6 fo modify a hand
movement?<br>

This depends on the design of the font. For ligature based fonts,
every valid combination needs to be explicitly defined.<br>
<br>
The Unicode 8 based ligatures are defined in a 1.3 MB file.<br>

<a class="moz-txt-link-freetext" href="https://github.com/Slevinski/signwriting_2010_tools/blob/master/source/signwriting_2010_unicode8.fea">https://github.com/Slevinski/signwriting_2010_tools/blob/master/source/signwriting_2010_unicode8.fea</a><br>
<br>
Here are the first few lines.<br>
<pre>feature ccmp {
sub u1DA8B u1DAA7 by S38b07;
sub u1DA8B u1DAA6 by S38b06;
sub u1DA8B u1DAA5 by S38b05;
sub u1DA8B u1DAA4 by S38b04;
sub u1DA8B u1DAA3 by S38b03;
sub u1DA8B u1DAA2 by S38b02;
sub u1DA8B u1DAA1 by S38b01;
sub u1DA8B by S38b00;
</pre>
Inside the font, each symbol glyph is named after the symbol key.
The Unicode 8 design is mapped to the symbol keys using CCMP
ligatures.<br>
<br>
When a mapping is unavailable, it will result in a dangling
modifier(s). Depending on the font, the modifiers by themselves may
or may not have glyphs defined.<br>
<br>
Movement symbol (U+1D988) doesn't have any mapping for F5. So for
the string "U+1D988 F5 R16", the only valid substitution will be
"sub u1D988 by S28800", which will results in the string (S28800 F5
R16). The symbol key is mapped directly to the symbol glyph and the
F5 and R16 are dangling.<br>

<div>2) F4 will act exactly as no-F (and F2=F5 and F3=F6)? or
will I get a "void" caracter, so I can't add F4 to a hand
movement? I think that you are using opentype to create a
good font for SW, right? I'm not very good in this field,
but I think that this problem belong to opentype not to
unicode, right? So what have you done with opentype....<br>

<br>
In the font that I created to support the Unicode 8 design, I did
not define custom glyphs for stand-alone modifiers. These modifiers
by themselves will use the default glyph, which is a small X. <br>

<div>3) If I'm a researcher and I need to find every single Hand
Movement with F2, how can I get also the one with F5 (F2=F5)
without going crazy doing strange queries... I reformulate...
is there something (not me!) that will know that HandMov+F2 is
the same that HandMov+F5 and will give me both when I just
serach HandMOv+F2?<br>

F2 does not equal F5, so this really shouldn't be an issue. I might
be missing something, so please ask again.<br>
