中文报错ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control chara

最近在研究python生成word文档，此处利用python-docx模块，发现含有中文时报错如下：

ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters

修改为如下格式，即可规避该错误

p = document.add_paragraph(u"哈哈 ")

看到有同学在问添加的字符串变量怎么办，以下代码是当时写的自动生成关于pbootcms漏洞报告函数，title_1是网站名称为中文，最终会经过处理写入文档，主要方法是    weak_des = u" " + title + u";" + ip_info，大家可参考下

def pbootcms(url, vul_payload, title_1, ip_info, lujing, vulname):
    wenjian=open("G:\\python\\info\\title_error.txt",'a+')
    # 去掉标题中的乱码字符串
    sub_str = re.sub(u"([^\u4e00-\u9fa5\u0030-\u0039\u0041-\u005a\u0061-\u007a])", "", title_1)
    if str("403") in str(title_1) or str("没有") in title_1 or "Not" in title_1 or str("Nginx") in title_1 or str(
            "503") in title_1  or str("500") in title_1 or str("抱歉") in str(title_1) or len(title_1) == 0:
        title="wrong"
