Sho (letter)

[1] It was similar in appearance to the Anglo-Saxon and Icelandic letter thorn (þ), which has typically been used to represent it in modern print, although they are historically unrelated.

It probably represented a sound similar to English "sh" ([ʃ]).

[1] Ϸ was added to Unicode in version 4.0 (2003), in an uppercase and lowercase character designed for modern typography.

The modern Cypriot Greek dialect also has a voiceless postalveolar fricative, represented with the combining caron ⟨ˇ⟩, by the authors of the "Syntychies" lexicographic database at the University of Cyprus, [4] e.g. μάσ̌σ̌αλλα [ˈmaʃːalːa] "mashallah".

When diacritics are not used, an epenthetic ⟨ι⟩ – often accompanied by the systematic substitution of the preceding consonant letter – may be used to the same effect, e.g. Standard Modern Greek χέρι [ˈçeɾi] → Cypriot Greek σιέρι [ˈʃeɾi].
