<div class="moz-cite-prefix">The easy answer is that these do not
consist of a single set. For example, the single-, double-line
regular-stroke symbols and their combinations, form a subset that
is supported by the DOS code page 437. Another common DOS code
page (850) has only the single-line ones. <br>

<div class="moz-cite-prefix">Those, as well as the heavy stroke or
mixed weight combinations are presumably supported somewhere else,
as are the curved corners. I don't know off hand what the
character sets are from which these were derived, but again, I
would not be surprised if they supported only a subset.</div>

<div class="moz-cite-prefix">The diagonals, therefore, are not
necessarily from any of those subsets, and therefore likely never
intended to be used to provide diagonal connections.</div>

<br>
<br>
if you look at the Box Drawing block, e.g.,
<a class="moz-txt-link-freetext" href="https://codepoints.net/box_drawing">https://codepoints.net/box_drawing</a>, every character goes through
the middle of the edges of an imagined rectangle around the glyph.
That is, apart from U+2571, U+2572 and U+2573, the diagonal lines.
Those touch exclusively the corners of said rectangle.
<br>
<br>
I fail to imagine how these three characters could ever attach to
any of the other characters in this block. Are they not meant to
do that or am I missing a trick here?
<br>
<br>
Thanks for any pointers!
<br>

Cheers,
