By default, the cute magnifying glass, truck, link, etc., emoticons shown as a part of
yarn‘s output in most samples only appears on OS X.
In recent versions of
yarn, this can be forced on non-Mac by running:
yarn config set -- --emoji true
In most non-Mac terminals, the emojis display in monochrome.
Conversely, these icons can be disabled (on any platform) with
yarn config set -- --emoji false.
