-/**
- * Truncates a UTF-8-encoded string safely to a number of characters.
- *
- * @param $string
- *   The string to truncate.
- * @param $max_length
- *   An upper limit on the returned string length, including trailing ellipsis
- *   if $add_ellipsis is TRUE.
- * @param $wordsafe
- *   If TRUE, attempt to truncate on a word boundary. Word boundaries are
- *   spaces, punctuation, and Unicode characters used as word boundaries in
- *   non-Latin languages; see Unicode::PREG_CLASS_WORD_BOUNDARY for more
- *   information. If a word boundary cannot be found that would make the length
- *   of the returned string fall within length guidelines (see parameters
- *   $max_length and $min_wordsafe_length), word boundaries are ignored.
- * @param $add_ellipsis
- *   If TRUE, add t('...') to the end of the truncated string (defaults to
- *   FALSE). The string length will still fall within $max_length.
- * @param $min_wordsafe_length
- *   If $wordsafe is TRUE, the minimum acceptable length for truncation (before
- *   adding an ellipsis, if $add_ellipsis is TRUE). Has no effect if $wordsafe
- *   is FALSE. This can be used to prevent having a very short resulting string
- *   that will not be understandable. For instance, if you are truncating the
- *   string "See myverylongurlexample.com for more information" to a word-safe
- *   return length of 20, the only available word boundary within 20 characters
- *   is after the word "See", which wouldn't leave a very informative string. If
- *   you had set $min_wordsafe_length to 10, though, the function would realise
- *   that "See" alone is too short, and would then just truncate ignoring word
- *   boundaries, giving you "See myverylongurl..." (assuming you had set
- *   $add_ellipses to TRUE).
- *
- * @return string
- *   The truncated string.
- *
- * @deprecated in Drupal 8.x-dev, will be removed before Drupal 8.0.0.
- *   Use \Drupal\Component\Utility\Unicode::truncate().
