编码错误：输入转换因输入错误而失败，使用Flask和BeautifulSoup时字节为0x9D 0x29 0x2E 0x20

Question

我正在制作一个Web Scraper来抓取GSoC组织信息。 我试图通过使用Flask在浏览器上显示输出。 但是我收到了这个错误：

(venv) astanwar99@astanwar99-Predator-G3-572:~/DEVSPACE/WebDev/Web_Scrap_GSOC/GSoC-OrganisationScraper$ python scrape.py
* Serving Flask app "scrape" (lazy loading)

scrape.py:43: UserWarning: No parser was explicitly specified, so I'm 
using the best available HTML parser for this system ("lxml"). This 
usually isn't a problem, but if you run this code on another system, 
or in a different virtual environment, it may use a different parser 
and behave differently.

The code that caused this warning is on line 43 of the file scrape.py. To get rid of this warning, pass the additional argument  
'features="lxml"' to the BeautifulSoup constructor.

soup = BeautifulSoup(html)
encoding error : input conversion failed due to input error, bytes 0x9D 0x29 0x2E 0x20
encoding error : input conversion failed due to input error, bytes 0x9D 0x29 0x2E 0x20

基本上错误是：

编码错误：由于输入错误，输入转换失败，字节0x9D 0x29 0x2E 0x20

编码错误：由于输入错误，输入转换失败，字节0x9D 0x29 0x2E 0x20

我在谷歌搜索，结果与BeautifulSoup有关，但是当我在终端上显示输出时脚本正在工作，所以我不确定问题是否与BeautifulSoup有关。 这是我的代码：

scrape.py

            tech = []
            for tag in tags:
                tech.append(tag.text)

            output_dict = {

    return render_template('genData.html', genData=genData_list)


if __name__ == '__main__':
    app.run(debug=True)

home.html的

<!DOCTYPE html>

    </head>
    <body>

    <input type="button" id="start_output" value="START"></input>
    <div id="place_for_genData"></div>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

    <script>
    $("#start_output").click(function(){
        var status = true;

        $.ajax({
        url: "/genData",
        type: "get",
        data: {jsdata: status},
        success: function(response) {
            $("#place_for_genData").html(response);
        },
        error: function(xhr) {
            //Do Something to handle error
        }
        });
    });
    </script>
    </body>
</html>

genData.html

<label id="value_lable">
{% for data in genData %}
    {{ data }}<br>
{% endfor %}
</label>

编辑：这是在终端上打印输出的原始脚本。

programs that allow working with 3D point cloud data. The tools include a powerful and efficient 3D point cloud viewer called \"show\" which is 
 able to open point clouds containing millions of points even on older graphics cards while still providing high frame rates. It provides bindings 
 for ROS, the Robotic Operating System and for Python, the programming language. Most of the functionality of 3DTK is provided in the form of 
 \"tools\", hence the name which are executed on the command line. These tools are able to carry out operations like simultaneous localization and 
 mapping (SLAM), plane detection, transformations, surface normal computation, feature detection and extraction, collision detection and dynamic 
 object removal. We support Linux, Windows and MacOS. 3DTK contains the implementation of several complex algorithms like multiple SLAM and ICP 
 implementations as well as several data structures like k-d trees, octrees, sphere quadtrees and voxel grids. The software is home of the 
 implementation of algorithms from several high impact research papers. While the Point Cloud Library (PCL) might be dead, 3DTK is alive and 
 actively maintained by an international team of skilled researchers from all over the world, ranging from Europe to China. Know-how from 3DTK 
 influenced several businesses from car manufacturers to mineral excavation or archaeological projects."}

随意建议一些其他替代或解决方案。 我只想在localhost上显示我的输出。

从警告看起来您需要每次都指定解析器

soup = BeautifulSoup(html, 'lxml')

你有一行当前读取（ for org in orgs:内部）：

soup = BeautifulSoup(html)
