Forward email cannot overtake special characters

Hello,

I have received an email which i want to forward.
The original email looks like this, it has this french characters: é à and also the apostroph

I then click on “forward” and this is the current result: the french characters are destroyed and replaced by other signs…

Which setting should i “improve” to avoid this issue?

Many thanks in advance.
