Unicode is a liberation for anyone old enough to handle a large number of incompatible character sets; A real character set to contain all characters. We have too many Unicode characters to use, so exploring the fuzzy corners that can be rendered as Unicode glyphs on the screen is itself a fascinating pursuit. So many different character sets are combined to form the Unicode standard, and there are many unusual characters to choose from, which is one of the characters studied in detail by [Jonathan Chan].
U + 237C ⍼, or right angle with downward zigzag arrow, is a mysterious Unicode symbol with no known purpose and unknown source. Xkcd describes it as a spoof of “Larry Potter”, but as Jonathan’s analysis shows, it has proved impossible to narrow its source range. Mysterious sacrificial symbols? Or, in an economy with a downward trend in time, what will happen to fiscal growth? Anyway, when its lineage dates back to the early 1990s and there is no answer, there seems to be a story behind it.
Hackday readers continue to amaze us with their extensive knowledge, originality and experience, so we think that some of you may turn over and over, take out a dusty computer manual from the bookshelf and tell us the story behind this elusive symbol. We would like to hear the following comments.
At the same time, if Unicode excites your interest, we have studied it carefully in the past.
