Similar.
Compiler error while working on some ObjC. Nothing obviously wrong. Copy-pasted the line, same thing on the copy. Typed it out again, no issue with the re-typed version. Put the error version and the ok version next to each other, apparently identical.
I ended up discovering I'd accidentally lent on the option key while pressing the "-"; Monospace font, Xcode, m-dash and minus looked identical.
This issue also exists with (so called) "smart" quotes.
I once spent a day debugging some data that came from an English doc written by someone in Japan that had been pasted into a system and caused problems. Turned out to be an en-dash issue that was basically invisible to the eye. No love for en-dash!
