How to format the day of the week to not show symbol in PHP

Question

How to exchange the symbol � appearing on Tuesday by a C?

My code below:

<?php 
    setlocale(LC_ALL,"pt_BR", "pt_BR.utf-8", "portuguese" );
    date_default_timezone_set('America/Sao_Paulo');
    echo ucwords(strftime("%A "));
    $dt = date('d/m/Y', time());
    echo $dt;
?>

Answer 1

In this case, just call the function utf8_encode

Thus remaining:

echo ucwords(utf8_encode(strftime("%A ")));
