The new backend, YADT, supports translation but may contain some bugs. We appreciate your patience as we work on fixing them gradually.

我依然怀疑是字体缺失，请问pdf2zh需要使用哪些字体，我想去下载系统字体试试能否解决问题

[hellofinch]

https://github.com/Byaidu/PDFMathTranslate/blob/main/pdf2zh/high_level.py#L382
可以参考这里，这里下载了所需要的字体。

[sainnodel]

https://github.com/Byaidu/PDFMathTranslate/blob/main/pdf2zh/high_level.py#L382
这里， URL_PREFIX = "https://github.com/timelic/source-han-serif/releases/download/main/"
这一行指向的url提示404？没有理解是什么情况

[awwaawwa]

This is the URL prefix. Other strings will be appended to this function, and only after appending will it become a complete URL.

[sainnodel]

我手动下载了GoNotoKurrent-Regular.ttf放进了字体册，但是结果依然没有变化。无论如何还是非常感谢你的帮助。

[hellofinch]

https://github.com/Byaidu/PDFMathTranslate/blob/main/pdf2zh/high_level.py#L405
这里做了URL的拼接，最终请求的是一组内容。

[awwaawwa]

这个不是缺字体，是字体子集化失败。这块把fallback改成false吧，应该是能好， @hellofinch 有空试试？

[sainnodel]

请问我的情况还有解决的办法吗？@awwaawwa 请教您一下
YADT不太明白应该怎么使用，还是希望在pdf2zh内解决问题

[awwaawwa]

等这个搞完吧 #586

pdf2zh 2.0 will use YADT as its core, focusing on self-deployment related matters.
