Here are the Unicode names of the characters not found in the conventional Greek alphabet:

upper case			value	lower case
Table N-4-a
Unicode name	source	result	value	result	source	Unicode name
Greek letter stigma	`Ϛ`	Ϛ	6	ϛ	`ϛ`	Greek small letter stigma
Greek letter digamma	`Ϝ`	Ϝ	6	ϝ	`ϝ`	Greek small letter digamma
Greek letter koppa	`Ϟ`	Ϟ	90	ϟ	`ϟ`	Greek small letter koppa
Greek letter archaic koppa	`Ϙ`	Ϙ	90	ϙ	`ϙ`	Greek small letter archaic koppa
Greek letter sampi	`Ϡ`	Ϡ	900	ϡ	`ϡ`	Greek small letter sampi
Greek capital letter archaic sampi	`Ͳ`	Ͳ	900	ͳ	`ͳ`	Greek small letter archaic sampi

There can be confusion between the following two characters, because the glyphs are similar:

Greek small letter stigma ϛ (ϛ)
Greek small letter final sigma ς (ς)

Sometimes encountered is the Greek zero sign 𐆊 (𐆊).

Two more characters are essential:

The Greek (upper) numeral sign, following a letter, indicates that the letter represents the number indicated in the table above.
The Greek lower numeral sign, preceding a letter, indicates that the letter represents the number indicated in the table above, multiplied by a thousand.

Examples:

Unicode name	source	result	source	result	value
Table N-4-b
Greek numeral sign	`ʹ`	ʹ	`Δʹ`	Δʹ	four
			`Κʹ`	Κʹ	twenty
			`Ωʹ`	Ωʹ	eight hundred
Greek lower numeral sign	`͵`	͵	`͵Δ`	͵Δ	four thousand
			`͵Κ`	͵Κ	twenty thousand
			`͵Ω`	͵Ω	eight hundred thousand

There is a risk of ambiguity because of the syntax; an example is ͵ΡΛΘʹ. Not apparent is whether the lower or upper mark applies to Λ:

If lower, the value is 100,000 + 30,000 + 9 = 130,009.
If upper, the value is 100,000 + 30 + 9 = 100,039.
