Environment

Describe the bug
The swedish alphabet has three characters that English does not have, å ä ö. I can input ä and ö but not å. When pressing the character å (right of the p-key on a Swedish keyboard) the letter å is not printed and the output in the terminal is the following:

[server] WARN: Could not inject char u+00e5
