Можете ли вы включить неподдерживаемые сценарии в \ p {язык}?

Question

Использование Drupal 8.x, PHP 7

Работа с некоторой заменой регулярных выражений, которую я нашел \p{Language}, например \p{Armenian}.

Мне нравится этот подход, потому что он оправдан, я могу сказать: «Это поддерживает официальные сценарии и все ...» и кажется достаточно гибким. Но ... \p{English} в качестве значения возвращает ошибку.

Чтобы справиться с этим, я попробовал код ниже:

// Get current site language.
$language =  \Drupal::languageManager()->getCurrentLanguage()->getName();

// Filter by Language.
if ($language == 'English') {
  // Search for any word that starts with '@' in English.
  $pattern = '/@(\w+)/';
}
else {
  // Search for any word that starts with '@' by language.
  $pattern = '~@(\p{' . $language . '}+)~u';
}

// Execute replacement.
$replaceText = preg_replace($pattern, $replacement, $text);

Есть ли способ расширить на \p{} или включить другие языки?
