Hello!
So I am writing here because I am very puzzled, and I have no more ideas of what might be happening.
About 2 years ago I designed a cursive typography for an educational program. It has about 3 versions of each letters to make sure that they are always linked whatever comes before or after.
you can test it here: Arcobaleno
On this webpage, the accentuated capital letters have their accents : É È Â Ö …
When I test them on my computer I always have the accents on the capital letters, on Illustrator, Word, Pages… I have no issue! I am on macOS
But my client, who uses Windows, cannot get the accentuated capitals on Word. When he writes È in an other typeface llike times new roman, the letter is accentuated, but when using Arcobaleno it looses the accent.
I don’t understand why, I’d love to hear your ideas / solutions!
