// But when we print this in the terminal on my computer we don't see that character.

// Look here:

// https://www.utf8-chartable.de/unicode-utf8-table.pl

// This is because my computer prints out Strings in utf-8.

// As shown in the link above, the utf-8 encoding for \u0080 is \xc2\x80

// but the font package I have installed on my computer does not print that value

// So we just see a 'missingno' like in pokemon.
