 ANTON  Actually yes, but the problem is that we don't meet it as such - at least not too often  . The examples of yours are of short vertical lines, not of tall ones.


One explanation though of why the vertical in gallows is tall is that it is deliberately made tall in gallows so as the "gallows coverage" can be enforced (I believe I already proposed that somewhere in the Forum). So, the vertical is natively short, but it is made tall in the gallows specifically for the "gallows coverage" to be possible.

But the standalone short vertical is also extremely rare, I suppose. This speaks against it being a "basic" shape. A shape that is extremely rare is not a "basic" one.

I think, what the short and long vertical line one and the same character.
The fact that vertical line can change its height and grow up in the leg of "the gallows" it can be assumed from Example 36, there the gallows is written in two steps.
Code 140 extended EVA (Fig 20, 21) with the vertical line (13) form a sickle - a code 206 extended EVA (Figure 22 - 28 ...). Look at the typical little tail (red arrow).
Figures 25, 26, 27 - the same word.
 I (temporarily) to distinguish between the apostrophe and code 140 - a large apostrophe "¬" in the glyphs "r", "s" and "sickle".

Sickle is also bigrams (syllable) "|" + "¬".
