@lizardsquid no, there's one before the square root
@Felthry I must have put that in accidentally - it doesn't even show up on my screen
@lizardsquid that is several kinds of weird!
@Felthry @lizardsquid Might just be something that neither your device nor mine is supporting correctly, but that the lizardsquid's is. Some of the zero-width-joiners are less commonly supported.
@salameleon @Felthry no I probably just typed <compose> \ / and forgot about it because nothing appeared (for some reason unicode boxes don't appear here, they're just invisible)
@lizardsquid @Felthry Then that is indeed several kinds of weird all at once!
@salameleon @lizardsquid it is quite clearly U+2340 : APL FUNCTIONAL SYMBOL BACKSLASH BAR though
if it was just mojibake I don't think http://www.babelstone.co.uk/Unicode/whatisit.html would say it is what it looks like
@Felthry @lizardsquid "Functional symbol backslash bar" sounds like some incredibly geeky avant garde establishment.
@lizardsquid what is that first symbol, I don't recognise it
