Lady, EVOLVED 
orthography
proposal to replace
Sh sh / Zh zh / Ch ch
with
Ƨƨ / Ʒʒ / Ꜭꜭ
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
Follow
orthography
Ʒʒ for Zh is well‐established; Ꜭꜭ for Ch is cute because it can be interpreted as “J with flag”
orthography
Şş is a cute but traditional option for Sh if you really care about having the curved descender
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)
