orthography
Sh is the difficult one here; i’m also fond of £ſ as an option
not too fond of Ʃʃ though; the capital is decidedly non‐latinate
orthography
(if you’d rather steal from cyrillic there’s Ɥɥ for Ch but Ꜭꜭ resembles others in the series a lot better)
(yep! either way it looks like a 4)
orthography
Şş is a cute but traditional option for Sh if you really care about having the curved descender
orthography
Ʒʒ for Zh is well‐established; Ꜭꜭ for Ch is cute because it can be interpreted as “J with flag”
