Unicode Greek mapping

The following characters are allowed in the transcription system using the ancient Greek section of Unicode.

Individual alphabetic characters

For the twenty-four individual alphabetic characters of the Attic-Ionic alphabet, the twenty-four upper-case Unicode code points 0391 - 03A1 and 03A3 - 03A9 may be used. For equivalent lower-case characters, the twenty-five lower case Unicode code points from 03B1 - 03C9 may be used. Either 03C2 (final sigma) or 03C3 (sigma) may be used for the character sigma; both are mapped to ASCII s.

Vowels combining with iota subscript, diaeresis, accents and breathings

A GreekString may be individual Greek vowel characters together with the combining Unicode codepoint for smooth or rough breathing, the three accent characters, iota subscript and diaeresis. Alternatively, a GreekString may use the equivalent Unicode precombined characters.

Punctuation

The following punctuation characters are allowed:

• period . (= \u002E)
• comma , (= \u002C)
• high stop · (= \u0387)
• question mark ; (= \u037E)

Elision

The elision character is transcribed in both ASCII and Unicode Greek transcriptions with the apostrophe character ' (= \u0027).

Unicode output

Whether constructed from beta-code or unicode source string, Greek Strings can be converted to Unicode in NFC form, except that two code points are maintained without normalization: Greek high stop and Greek question mark.
