Hi Charles,
The symbols in the email are "0.7" in size. I prepared the email using
the SignWriting Image Server. My development version of SWIS can
produce both the cartesian and polar markups.
Here's the raw polar markup:
B???330°16???129°14 B???169°21???252°6???80°11???19°21
Once I can get a font file created, the above markup will show the
actual symbols rather than the unknown code point boxes.
To fake it, I deleted the unknown code point boxes so I could replace
them with the symbol graphics.
In SWIS, I used the Symbols page. I changed the size to ".7" and press
view. Then I dragged the symbols to the desktop. Then from the desktop
into the email.
Regards,
-Steve
