U1F00

U+1F00 is a Unicode code point in the Greek Extended block, which runs from U+1F00 to U+1FFF. It encodes the Greek small letter alpha with psili, its official Unicode name being GREEK SMALL LETTER ALPHA WITH PSILI. This letter is a precomposed character used to represent a specific diacritic pattern of ancient and polytonic Greek, where psili denotes a smooth breathing mark over the initial alpha.

In terms of properties, U+1F00 is categorized as a lowercase letter (Ll) in the Greek script. It is not a combining character and is intended to be used as a single typographic unit within Greek text. The character appears in scholarly editions and digital texts that preserve polytonic orthography, though it is rarely needed for everyday modern Greek.

Encoding and representation details: in UTF-8, U+1F00 is encoded as the three-byte sequence E1 BC 80. In HTML and XML, it can be referred to by the numeric character reference ἀ. In many fonts, support for the full set of Greek Extended characters depends on font coverage, so rendering may vary across browsers and platforms.

Related code points include other precomposed Greek letters with diacritics in the same area of the Greek Extended block (for example, U+1F01, U+1F02, etc.). These characters collectively provide a set of historically attested Greek letters used in academic works on classical and Hellenistic texts.
