Cannot use unicode in fields 😭

Emoji work fine if downloaded from the gui, but no output on the CLI if used. [MRE](https://stackoverflow.com/help/minimal-reproducible-example):

``` bash
# fails
curl -LG https://zerocal.shuttleapp.rs/ -d title=Valid -d desc=🍺+to+catch+up!
# works
curl -LG https://zerocal.shuttleapp.rs/ -d title=Valid -d desc=beers+to+catch+up!
