您可以在\ p {Language}中包含不受支持的脚本吗？

Question

使用Drupal 8.x，PHP 7

使用某些正则表达式替换，我发现\p{Language}，例如\p{Armenian}。

我喜欢这种方法，因为它是可以辩护的，我可以说“这支持官方脚本，仅此而已...”，而且看起来足够灵活。但是... \p{English}作为值会返回错误。

为解决这个问题，我尝试了以下代码：

// 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);

是否可以扩展\p{}或合并其他语言？
