@dmself @futurebird I use a password manager that for some reason chose a font where these symbols (and possibly the vertical pipe |) are identical.

In related news, this is why I tell my computer science students not to use a lower-case L (l) as a variable name. I was shocked when I ran across an introductory machine learning book that, in the first chapter, had not one (1) but five (5) variables with this name -- they differed only in font!
