Don't know what the Unicode rules are, but the answer is no. The final
sigma form is not used if the sigma is in a medial position in the word but
at the end of the line (e.g., when it occurs at the point of hyphenation in
a hyphenated word at line end). Also, there is no reason why a consonant
other than rho should be followed by a combining diacritical mark, except
say an underdot for use in papyrological or epigraphical texts.
The upper case sigma is the same regardless of position; there is no
differentiation between upper case final sigma and upper case initial/medial
sigma.
If a font uses the lunate sigma for the initial/medial form, it must use it
for the final form as well, and vice versa.
Hope that helps,
Patrick Rourke
