Font issue. Some characters are displayed as "?"


Font issue in some Greek characters.

To Reproduce…

Steps to reproduce the behavior:
There are no specific steps that can reproduce the issue. Just receiving emails from specific servers and the display is problematic.

Expected Behavior

Just displaying correctly all text.


Here is the problematic character display in MailSpring

Here is the same emails how they are displayed in in macOS


  • OS and Version: macOS 10.13.6 (but tested the same in Ubuntu, too)
  • Mailspring Version: 1.7.6

Additional Context

It seems that the problem is character encoding of the servers which sending the emails. I noticed that the same problematic characters that missing from these specific emails, they are present in other emails from other servers.

But in default Mail application of macOS, all the emails are displayed correctly, so something here is happening either the font support or encoding
