Now, however, it has just gotten harder to detect such phishing attacks with just your eyes.

To make matters worse, even browsers are no help at all.

These “homograph” phishing URLs, for all intents and purposes, looks exactly like a regular, safe URL.

And, unfortunately, they are taking advantage of the fact that computers these days can display more languages and characters than you might even be aware of.\

The Internet has made the world a smaller place and has, therefore, made it imperative that computers support more than just the limited character set of the English language.

The Unicode standard wad developed to go beyond the old ASCII character set to include all sorts of characters, symbols, and even emojis.
