[iOS Client] Cannot mention role with space and quote

We had a role such as @Chevaliers d’Arkein
Using the iOS App, the autocomplete returns this role and it can be selected. However, when the post is sent, the role is not mentionned.
On the other hand, Desktop and Android clients are fine the role can be selected and the mention works.

Note : Version seems to be 42.0 (installed today), iOS 14 on an iPhone SE.
