I was a bit confused at first since I only knew of "unum" as referring to John Gustafson's research into alternative floating point number representations (compared to the IEEE one we're all familiar with), but this looks quite handy!<p>> <i>Enter unum, a stand-alone utility program written in portable Perl which allows you to look up Unicode and HTML characters by name or number, and interconvert numbers in decimal, hexadecimal, and octal bases.</i><p>Speaking of "looking up by name", I recently discovered that when using any modern emoji picker, their search functions only work by name, barely contain any synonyms (which would help a lot there), and don't even support <i>searching by emoticons</i>. The last bit really surprised me at first - surely searching ":)" or ":-)" should result in a smiley.<p>I can only assume that this is because most emoji pickers work by automatically converting the unicode tables, since manually adding synonyms would be an incredible hassle.
