UniGreek Mac is a free utility for converting beta code to polytonic Greek script as you type.

The original UniGreek application was conceived by Randy Hoyt. Randy developed a web-based version of the application which is now hosted at typegreek.com.

If you are on a Windows PC or Linux computer, an older version of UniGreek is available.

Computers view letters as numbers. A character-encoding standard identifies which number represents which character. For example, the common ASCII character set represents an uppercase A as number 65. Most character-encoding systems use one byte and provide only 256 possible characters. These encoding standards do not have enough characters to handle all the polytonic Greek characters.

Beta code was developed to overcome this problem. Beta code is a standard way to represent Greek characters as a combination of Roman characters and punctuation. For example, ἀ is represented in beta code as a) — a for alpha and ) for smooth breathing. Beta code provided a way to type and store Greek texts digitally, but it is not really Greek and it is very difficult to read texts typed in beta code.

Enter Unicode

The Unicode standard provides a much better alternative to store, share, and display Greek texts. Unlike most character encoding standards, the Unicode standard use two bytes and provides over sixty-five thousand possible characters.

Since keyboards do not have enough keys to represent every polytonic Greek character, beta code still works as an easy-to-learn way to type polytonic Greek. UniGreek converts your beta code keystrokes into Greek characters as you type, so you never have to see the beta code; it looks like you are typing directly in Unicode Greek! These characters can then be copied and pasted into any Unicode-compliant application.
