Georgian is similar, but different. It also incorporates circles and vertical lines, but
it has fewer vertical lines, and many more c-shaped semi-circles.
Almost all Oriya letters have rounded tops. There are also a lot of circles, "n" shapes,
and angled or very short straight lines
Most Thai letters have a small circle or two attached to them somewhere. Also,
every single letter has at least one straight vertical line in it, and most have two.
Also, similar to Oriya, the majority of them have rounded tops.
Arabic has many large cup shapes, many small vertical hooks, and of course, lots of
Chinese has many straight vertical and horizontal lines, as well as gently-curving
Glagolitic has circles and triangles everywhere. Yet, oddly enough, there is no letter
that is just O or Δ.
Even something like Egyptian hieroglyphics reveals common patterns. looking
closely at a lot of signs will reveals many curves, including many S curves, that
gradually become wider and more open or flat on one side, sort of like part of a
Mayan, by contrast, tends to favour very blunt curves. Nearly every round shape is
squared off, like a square with rounded corners. As a result, there are very few real
circles in Mayan, and all that do exist are small.
2. Decide which strokes appear infrequently or not at all
It should come as no surprise that if some stroke types are frequent, others may not
be so frequent, or may even be entirely absent. Let's take a look:
No Latin letters have very open curves, like (. There are also very few horizontal
lines: in the lower-case letters, horizontal strokes appear only in e, f and t; in upper
case, only A, E, F, G, H, L, T and Z.
Chinese characters entirely lack tight curves and circles
