Greek Extended is a Unicode block containing the accented vowels necessary for writing polytonic Greek. The regular, unaccented Greek characters as well as the characters with tonos and diaeresis can be found in the Greek and Coptic (Unicode block). Greek Extended was encoded in version 1.1 of the Unicode Standard. As an alternative to Greek Extended, combining characters can be used to represent the tones and breath marks of polytonic Greek.

Note: [1][2]

In this block, the letters with oxia (acute accent) and no other accent are not used in any of the Unicode normalizations. Decomposition of U+1F71 GREEK SMALL LETTER ALPHA WITH OXIA, for example, yields U+03B1 α GREEK SMALL LETTER ALPHA followed by a U+0301 ◌́ COMBINING ACUTE ACCENT, while composition yields the same letter with tonos, U+03AC ά GREEK SMALL LETTER ALPHA WITH TONOS, from the Greek and Coptic block.
