For anyone old enough to have worked with the hell of multiple incompatible character sets, Unicode has been a liberation; a true One Character Set To Contain Them All. We have so many Unicode characters to play with that there’s a fascinating pursuit in itself in probing at the obscure corners of what can be rendered on screen as a Unicode glyph. With so many disparate character sets having been brought together to make the Unicode standard there are plenty of unusual characters to choose from, and it’s one of them that [Jonathan Chan] has examined in detail.
U+237C ⍼, or the right angle with downwards zigzag arrow, is a mysterious Unicode symbol with no known use and from an unknown origin. XKCD featured it as a spoof “Larry Potter”, but as [Jonathan]’s analysis shows it’s proving impossible to narrow down where it came from. Mystical cult symbol? Or perhaps fiscal growth in an economy in which time runs downwards? Either way, when its lineage has been traced into the early 1990s with no answer to the question it appears that there may be a story behind it.
Hackaday readers never cease to amaze us with the breadth of their knowledge, ingenuity, and experience, so we think it’s not impossible that among you there may be people who will turn and pull a dusty computer manual from the shelf to give us the story behind this elusive glyph. We’d love to hear in the comments below.
Meanwhile if Unicode sparks your interest, we’ve given it a close look in the past.
Thanks [Jonty] for the tip.
