Emails are rendered with unexpected characters

[msp301]

Describe the bug
Sometimes emails include unexpected characters e.g. Hi  is rendered as Hi .

To Reproduce
Steps to reproduce the behavior:

1. Get pinbox-server to return email content including Hi  in a HTML email
2. View content through Pinbox UI
3. Unexpected Â gets included

Expected behavior
Email content to match the text as is in the email: Hi 

Desktop (please complete the following information):

• OS: Ubuntu 18.04
• Browser: Chrome
• Version: 75.0.3770.100

Additional context
This feels like some form of white-space issue or similar.
Just reading in a small assortment of real emails should trigger the issue, as it seems fairly common for me.
