Hyphen is being replaced by $'\342\200\224...' in bash

I've created a bash script to start a network computer if it is sleeping, then start a streaming client. However, as the script executes the final command to run the streaming client, each cli option with a hyphen becomes wrapped in

$'\342\200\224'

. E.g.

-resolution

becomes

$'\342\200\224resolution'

. Specifically, this command in the script: /Applications/Moonlight.app/Contents/MacOS/Moonlight stream "$_target_computer_ip" "$_moonlight_app_name" —resolution "$_moonlight_resolution" —fps "$_moonlight_fps" &>/dev/null & executes in the shell as: /Applications/Moonlight.app/Contents/MacOS/Moonlight stream 192.168.1.30 mstsc.exe $'\342\200\224resolution' 1920x1024 $'\342\200\224fps' 30 I've tried escaping the hyphen as \-, but that just changes the output to

$'?\200\224

. What am I doing wrong? Here's the full script:

#!/bin/bash
set -x

_target_computer_ip='192.168.1.30'
_target_computer_subnet='192.168.1.255'
_target_computer_mac='2C:F0:5D:27:7C:95'

_moonlight_app_name='mstsc.exe'
_moonlight_resolution='1920x1080'
_moonlight_fps='30'

if ping -c 1 -W 1 "$_target_computer_ip"; then
  echo "is alive"
else
  echo "nope"
  wakeonlan -i $_target_computer_subnet $_target_computer_mac
fi

/Applications/Moonlight.app/Contents/MacOS/Moonlight stream "$_target_computer_ip" "$_moonlight_app_name" —resolution "$_moonlight_resolution" —fps "$_moonlight_fps" &>/dev/null &

And the full command output:
