@tedmielczarek Oooh, unicode archaeology! Added in Unicode 5.1, and I think this is the original proposal: https://www.unicode.org/L2/L2006/06269-add-roman.pdf
From the doc:
Roman inscriptions and coins from the imperial period make use of a palm branch character [...] Because the palm branch is used to separate words or sections of text, it should be regarded as a punctuation character rather than as a symbol. [...] It would logically be placed in the Supplementary Punctuation range.
@dolske
I have not thought about it until this instant, but I would have assumed that a straightforward site with every Unicode symbol and its meta data* world exist, no? Seems like the sort of thing the internet nerd hive mind would have done basically from day one.
