How Can I Truncate a Multibyte String While Preserving Word Boundaries?

Multibyte String Truncation with Word Boundary Control

Question:

How can I truncate a multibyte string to a specified number of characters, maintaining word boundaries?

Steps for Truncation:

1. Calculate the maximum truncation length by subtracting the length of the terminator string from the desired character count.
2. Check if the string is longer than the maximum length; if not, return the unchanged string.
3. Find the last space character within the calculated truncation length.
4. Truncate the string at the last space character or the calculated length if no space is found.
5. Append the terminator string to the truncated string.
6. Return the modified string.

Implementation (Using mb_strimwidth for Multibyte Character Support):

function truncate_with_words($string, $chars = 50, $terminator = '...') {}
