Yahoo mail in google chrome - language codification not working for sender name - PT BR symbols (portuguese brazilian)

On yahoo mail on google chrome, the symbols of portuguese language (such as "´" or "~") appear correctly on the subject of the email and on basically everything in the website except for the sender's name. A strange symbol substitutes it, maybe a chinese one?

Encoding of google chrome itself is set to UTF-8, so is yahoo mail. Every other website has no issue.

I realise this is an old version of google chrome yet this is my grandmother's computer who is not particularly open to change.

I would be very happy if someone were to find a solution to this issue.

Highlighted the fact that the symbol "~" appears normally on the subject of the email but NOT on the sender's name
