Answer 1

I have coded it in python, as you didn't specify anything. The idea is here.

def remove_non_english_chinese(text):
    # Use a regex pattern to match any character that is not a letter or number
    pattern = r'[^a-zA-Z0-9\u4e00-\u9fff]'

    # Replace all non-English and non-Chinese characters with an empty string
    return re.sub(pattern, '', text)
