How can PHP developers ensure consistent UTF-8 encoding across their projects?

PHP developers can ensure consistent UTF-8 encoding across their projects by setting the default encoding to UTF-8, using the mb_internal_encoding() function, and ensuring that all input and output is properly encoded and decoded using mb_convert_encoding(). 

// Set default encoding to UTF-8
mb_internal_encoding("UTF-8");

// Convert input to UTF-8
$input = mb_convert_encoding($input, "UTF-8");

// Convert output to UTF-8
$output = mb_convert_encoding($output, "UTF-8");
