ISO 5428:1984, Greek alphabet coded character set for bibliographic information interchange, is an ISO standard for an 8-bit character encoding for the modern Greek language. It contains a set of 73 graphic characters and is available through UNIMARC. In practice it is now superseded by Unicode.
ISO/IEC 8859-7:2003, Information technology — 8-bit single-byte coded graphic character sets — Part 7: Latin/Greek alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as Latin/Greek. It was designed to cover the modern Greek language. The original 1987 version of the standard had the same character assignments as the Greek national standard ELOT 928, published in 1986. The table in this article shows the updated 2003 version which adds three characters (0xA4: euro sign U+20AC, 0xA5: drachma sign U+20AF, 0xAA: Greek Ypogegrammeni U+037A). Microsoft has assigned code page 28597 a.k.a. Windows-28597 to ISO-8859-7 in Windows. IBM has assigned code page 813 to ISO 8859-7.
ISO-8859-7 is the IANA preferred charset name for this standard (formally the 1987 version, but in practice there is no problem using it for the current version, as the changes are pure additions to previously unassigned codes) when supplemented with the C0 and C1 control codes from ISO/IEC 6429.
Unicode is preferred to ISO 8859-7 or other Greek encodings in modern applications, especially on the Internet; meaning the dominant UTF-8 encoding for web pages (see also Greek alphabet in Unicode, for complete coverage, including for Ancient Greek Musical Notation, unlike for e.g. ISO 8859-7 and Windows-1253 that don't cover extras).List of International Organization for Standardization standards, 5000-7999

However, about 300 of the standards produced by ISO and IEC's Joint Technical Committee 1 (JTC1) have been made freely and publicly available.Sampi
Sampi (modern: ϡ; ancient shapes: , ) is an archaic letter of the Greek alphabet. It was used as an addition to the classical 24-letter alphabet in some eastern Ionic dialects of ancient Greek in the 6th and 5th centuries BC, to denote some type of a sibilant sound, probably [ss] or [ts], and was abandoned when the sound disappeared from Greek.
It later remained in use as a numeral symbol for 900 in the alphabetic ("Milesian") system of Greek numerals. Its modern shape, which resembles a π inclining to the right with a longish curved cross-stroke, developed during its use as a numeric symbol in minuscule handwriting of the Byzantine era.
Its current name, sampi, originally probably meant "san pi", i.e. "like a pi", and is also of medieval origin. The letter's original name in antiquity is not known. It has been proposed that sampi was a continuation of the archaic letter san, which was originally shaped like an M and denoted the sound [s] in some other dialects. Besides san, names that have been proposed for sampi include parakyisma and angma, while other historically attested terms for it are enacosis, sincope, and o charaktir.Windows-1253
Windows-1253 is a Windows code page used to write modern Greek. It is not capable of supporting the older polytonic Greek. It is not fully compatible with ISO 8859-7 because the letters like Ά are located at different byte values.
Unicode is preferred to ISO 8859-7 or other Greek encodings in modern applications, especially on the Internet; meaning the dominant UTF-8 encoding for web pages (see also Greek alphabet in Unicode, for complete coverage, including for Ancient Greek Musical Notation, unlike for e.g. ISO 8859-7 and Windows-1253 that don't cover extras).
