A common security issue is ‘spoofing’, the deliberate misspelling of a domain or user name to trick unaware users into entering an interaction with a hostile site as if it was a trusted site. To be effective, spoofing can be very approximate, e.g. using the digit ‘1’ instead of the letter ‘l’. The Unicode Standard contains many “confusables,” that is, characters whose glyphs, due to historical derivation or sheer coincidence, resemble each other more or less closely. Certain security-sensitive applications or systems may be vulnerable due to possible misinterpretation of these confusables by their users.
