This happens every time I tried to translate Japanese words. For example, I tried to copy this message "ごめんなさい、分からない言葉みたいです・・・。(Quote from my Twitter friend)" to Google Translate, and I replied to her in English. As if I tried to copy another different text, for example, I want to copy and paste the sentence "This is an example of a sentence", instead of " This is an example of a sentence, I got "ごめんなさい、分からない言葉みたいです・・・。" instead.
