Foreign character failure - unescape(encodeURIComponent(options.headers[key])); [Bug] about filepond HOT 3 OPEN

Thanks for reporting. So this doesn't happen when uploading without PATCH?

Hi Rik,

It relates to a header property Upload-Name. This only appears in the PATCH call and not the base networkcall if the file is small. When the filename has foreign characters, the "encodeURIComponent" and "unescape" cause the below corruption of file name which throws an error. It is browser related too, depending on how unescape has been implemented. Latest Chrome has the error.

As I understand it, unescape is deprecated and non-standard, which is possibly why this error has only recently happened.

In the below 24098_错误获取风险数据.png gets corrupted.

I believe it relates to this code here in sendRequest.js, where unescape and encodeURIComponent are incompatible. One encodes as unicode, the other is hexadecimal.
