如何从 Youtube Data API V3 获取多语言标题并将其写入 csv 文件以便可读

Question

我想从给定的播放列表中检索标题和 URL，并将其写入本地 csv 文件，以便在 Microsoft excel 中使用。到目前为止一切顺利，没有问题，我用https://developers.google.com/youtube/v3/code_samples/dotnet 的代码制作了一个.Net 控制台项目。 我的播放列表中的标题有多种语言，如德语、希伯来语、西班牙语和俄语。要编写 csv 文件，我在 c# 中使用 CsvHelper。问题是特殊的非英语字符在 csv 文件中显示为不可读的字符。这是我的德语播放列表代码，但它不能正确显示德语特殊字符。

我通过写入 SQL Express 数据库、定义列 nvarchar 解决了这个问题。这解决了语言问题。
