在Azure存储元数据中使用国际字符？

Question

When I run this request using this azure library:

blobURL.PutBlob(ctx, strings.NewReader("Some text"), azblob.BlobHTTPHeaders{}, azblob.Metadata{"Foo": "/愛知県/bar"}, azblob.BlobAccessConditions{})

I get this error:

===== RESPONSE ERROR (ServiceCode=AuthenticationFailed) =====

exit status 1

Is this because "/愛知県/bar" != "/愛知県/bar"? Do you see any way to set non-ascii character like "/愛知県/bar" as a metadata value?

Since you mentioned Go in the tag, I assume you are looking for using a transliterator, there is this one in github which you should try : https://github.com/rainycape/unidecode
