-# IMPORTANT-when capitalizing iota-subscript (0345)
-# It MUST be in normalized form--moved to the end of any sequence of combining marks.
-# This is because logically it represents a following base character!
-# E.g. <iota_subscript> (<Mn> | <Mc> | <Me>)+ => (<Mn> | <Mc> | <Me>)+ <iota_subscript>
-# It should never be the first character in a word, so in titlecasing it can be left as is.
+# IMPORTANT-when iota-subscript (0345) is uppercased or titlecased,
+# the result will be incorrect unless the iota-subscript is moved to the end
+# of any sequence of combining marks. Otherwise, the accents will go on the capital iota.
+# This process can be achieved by first transforming the text to NFC before casing.
+# E.g. <alpha><iota_subscript><acute> is uppercased to <ALPHA><acute><IOTA>
