jsPDF library cannot insert utf8 letters into pdf
提问by mpavlovic89
I'm struggling without success to use jspdf libraryin order to export html page as pdf file. There is one similar question here but bad answers. The problem is in UTF-8 characters, even I made all my documents utf8. What should I do to make this library (parall.ax/products/jspdf) insert letters such as ?,?,? into pdf?
我正在努力使用jspdf 库将 html 页面导出为 pdf 文件，但没有成功。这里有一个类似的问题，但答案不好。问题出在 UTF-8 字符中，即使我将所有文档都设为 utf8。我应该怎么做才能使这个库（parall.ax/products/jspdf）插入诸如 ?,?,? 变成pdf？
Here is the link where you can try this problem (http://balkanex.info/test/start.html), or just have a look on my code below and then go to the link. I must say that I am making local app so I cannot user servers advantages.
这是您可以尝试此问题的链接（http://balkanex.info/test/start.html），或者只需查看我下面的代码，然后转到该链接。我必须说我正在制作本地应用程序，因此我无法利用服务器优势。

This library doesn't support some of these letters. And the developers told that it will be accessible soon.
该库不支持其中一些字母。开发人员告诉它很快就会访问。
But, if you want to use these letters, you can make images that will replace some of the problematic letters.
但是，如果您想使用这些字母，您可以制作图像来替换一些有问题的字母。
For example, make the image of the letter ? and then, in the specific field you can change the letter with this image. It is quite a work. Therefore, I suggest you to change the library.
例如，制作字母的图像？然后，在特定字段中，您可以使用此图像更改字母。这是一个相当的工作。因此，我建议您更改库。
