我用python编写了它，因为你没有指定任何东西。

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)

您似乎要删除标点符号和空格：

> regex <- '[[:punct:][:space:]]+'
> gsub(regex, '', ori_string)
[1] "没awt中国sz"
