Just a hint, str_replace itself is utf-8 ready, thats why mb_str_replace does not exist.

@vadviktor @sgmurphy you are absolutely right! Just checked it with PHP 5.4

@vadviktor 👍

Иногда можно использовать и такой простой способ

// БЫСТРАЯ ЗАМЕНА МАКРОСА ДЛЯ МУЛЬТИБАЙТОВЫХ СТРОК
$title = 'Текст на русском и #NAME# теперь в строке';
$name = 'Мария';
$macros = '#NAME#';
$macLen = mb_strlen($macros);
$macPos = mb_strpos($title, $macros);
if($macPos !== false)
{
$start = mb_substr($title, 0, $macPos);
$end = mb_substr($title, $macPos + $macLen);
$title = $start.$name.$end;
}
echo $title; // Текст на русском и Мария теперь в строке
