Mailcatcher does not work with accents

[lupusellobo]

Operating System: Ubuntu 19.04
Vagrant Version: 2.2.4
Virtual Box Version: 6.0.6_Ubuntur129722

When you try to send an email with accents the following error is triggered:

/var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/message.rb:2032:in match: invalid byte sequence in US-ASCII (ArgumentError) from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/message.rb:2032:in match from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/message.rb:2032:in set_envelope_header from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/message.rb:2132:in init_with_string from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/message.rb:137:in initialize from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/mail.rb:51:in new from /var/lib/gems/2.4.0/gems/mail-2.7.1/lib/mail/mail.rb:51:in new from /var/lib/gems/2.4.0/gems/mailcatcher-0.7.1/bin/catchmail:59:in <top (required)> from /usr/local/bin/catchmail:23:in load from /usr/local/bin/catchmail:23:in <main>
Actually the solution is really easy but I'm not that technical in vagrant provisioning:
