File not being ignored by Guardfile

[kevinjcoleman]

Hello!

I'm using a new sync tool, mutagen.io, to ensure that changes are synced from my host to my docker instance and I'm having an issue with a temporary file called .mutagen-temporary-unicode-test-\xC3\xA9ntry0 that the sync tool is creating which is causing my guard instance to blow up with this error.

E, [2019-04-16T19:18:16.580106 #9673] ERROR -- : run() in thread failed: invalid byte sequence in US-ASCII:\n /usr/local/rvm/rubies/ruby-2.5.3/lib/ruby/2.5.0/pathname.rb:43:in `=~'

I've added ignore(/\.mutagen/) to my guardfile, but that doesn't appear to actually be ignoring it on the listener, you can see below that it is set correctly though. What am I doing wrong here? Thanks!
