Read the stack trace. It says something about "latin1". The problem is probably that your terminal is set to latin1 / iso-8859-1 encoding.

There would be a possibility to replace non-convertable characters with a "?", but that would be bad because then information would get lost and the tags aren't the same anymore. This is important information, not just logs, so I assume the output terminal/pipe is utf8-capable.

TLDR: Set your terminal to use UTF8 encoding.
