Special characters("â","é") not shown properly in the macro description for few languages

Few characters in French, Spanish and Portuguese are not being displayed properly in the macro description. For example character “é” is displayed as &eacute.
I have added the corresponding unicode value “\u00E9” in the fr_FR.json file but still it doesn’t show the correct result.

What is the correct way of displaying such characters?

I opened a bug ticket for this issue in the CONFCLOUD project https://jira.atlassian.com/browse/CONFCLOUD-72213
