I put a short link on a family thing and someone complained it didn't work. Turns out iOS OCR recognised a "-" as a "=", so this isn't just people typing it wrong. Now my short links implement case insensitivity and striping all non alphanumeric characters, i.e. a "-" is optional and any other symbol character is also stripped. nyc.gov seems to do case insensitivity but doesn't strip "-", so you do need the "-".
