Is this condition sufficient ?

If I read the https://www.php.net/manual/en/migration71.windows-support.php page, I get the impression an additional check may be needed against the value of the internal_encoding ini setting - and if that's empty, the default_charset ini setting - to verify it is set to UTF-8 ?

Also note that internal_encoding and default_charset were both only introduced in PHP 5.6: https://www.php.net/manual/en/migration56.deprecated.php#migration56.deprecated.iconv-mbstring-encoding

Same remark applies to the Code report change.

// Do not replace spaces on old PHP on Windows.
// Printing Unicode characters like '·' to Windows console only works since PHP 7.1.
unset($replacements[" "]);
}

if (in_array("\n", $exclude, true) === false) {
$content = str_replace("\n", "\033[30;1m\\n\033[0m", $content);
}
$replacements = array_diff_key($replacements, array_fill_keys($exclude, true));

if (in_array("\t", $exclude, true) === false) {
$content = str_replace("\t", "\033[30;1m\\t\033[0m", $content);
}
// Colour runs of invisible characters.
$match = implode('', array_keys($replacements));
$content = preg_replace("/([$match]+)/", "\033[30;1m$1\033[0m", $content);

This ends up adding more redundant colour codes on Windows for PHP < 7.1, similar to what is happening in the PHP tokenizer.


if (in_array(' ', $exclude, true) === false) {
$content = str_replace(' ', "\033[30;1m·\033[0m", $content);
}
}//end if
$content = strtr($content, $replacements);

return $content;
