I have blobs in a folder location and sometimes the blob name has some Chinese characters in it. For example, I have blob name as 项目.xlsx. Currently I am using downloadToFile method where am trying to download blob directly to my location. Here I couldn't specify UTF-8 encoding by any params or anything.

BlobClient blobClient = containerClient.getBlobClient(blobItem.getName());
blobClient.downloadToFile("C:/check/"+"项目.xlsx");

But in location if I give URL.encoder(项目.xlsx), its working fine, but I want the file name to be preserved. When I try to download, am getting unrecognized characters and marked with ? in the chinese characters file name.Is it possible by some way I can download the file to my local/azure file-share by having UTF-8 encoding so that Chinese characters are preserved? Please provide if any sample code is present.

    When I try to download, am getting unrecognized characters and marked with ? in the chinese characters file name WHERE are you getting them? What does Windows Explorer say? Commented May 27, 2024 at 10:39
  • @antoclinton – Jepp! To verify that, try it on a Linux system. Or write a simple Java program that does nothing else than creating a file with the name 项目.xlsx and write some stuff to it. And there are differences between FAT (in all its incarnations) and NTFS. (Sorry, I do not have any Windows box at hand to try it myself) Commented May 27, 2024 at 14:36

    @Venkatesan, you're somewhat repeating yourself, and inaccurately, as UTF-16 is used for file names afaik. It might be Ansi in certain limited areas Commented May 28, 2024 at 10:56
