Can't use a custom character set

[elad661]

$ /home/elad/.cargo/bin/txtpic --character-set "▀▀▂▃▄▅▆▇█▉▊▋▌▍▎▏▐░▒▓▔▕▖▗▘▙▚▛▜▝▞▟" ~/test.png 
error: The argument '--character-set <CHARACTERS>' cannot be used with '--preset <PRESET NAME>'

USAGE:
    txtpic <IMAGE> --character-set <CHARACTERS> --preset <PRESET NAME> --width <WIDTH>

For more information try --help
