Azure-cosmos-dotnet-v2: Request headers must contain only ASCII characters.

Hi!

I tested Microsoft.Azure.DocumentDB.Core 2.0.0-preview and got the exception below when executing: FeedResponse response = await query.ExecuteNextAsync();

System.Net.Http.HttpRequestException: Request headers must contain only ASCII characters.

Hi!

I used an old continuation token that included "Stöde" as item. I did reset the continuation token to null and it started to work again. I will wait and see if item gets encoded in the new version of document db.

Hi,

the problem still persists. I encountered a continuation token with UTF-8 characters today and it failed with the exception above. The item is "Läcker - Ola Arena".

The problem is that I have this problem on Azure even if I use Microsoft.Azure.DocumentDB.Core 1.9.1. It works on localhost with Microsoft.Azure.DocumentDB.Core 1.9.1.

A workaround is order by parameters that only contains ASCII characters.

Hi,
Just wanted to add in here I'm having the same issue.

[jezeri]

Hi,
I have the exact same issue using Microsoft.Azure.DocumentDB.Core 2.4.0.

[irriss]

same issue

[TanmayDharmaraj]

Same thing for me in Microsoft.WindowsAzure.Storage as well

[xiaohu0828]

same issue here. Any solution except avoid order by name?

[ysris]

Don't know if it can help, I fixed this error in my dotnet code using the following procedure :

For those who came accross this post for trying to send not extended ascii characters (as french accents, chinese characters etc...), here is a resume :

Modify your httpclient headers set from :
client.DefaultRequestHeaders.Add("YOUR_HTTP_HEADER", "yourvàluewithspécialcharacters");

To :
client.DefaultRequestHeaders.Add("YOUR_HTTP_HEADER", Convert.ToBase64String(Encoding.UTF8.GetBytes("yourvàluewithspécialcharacters")));

In my case it worked and fixed the HttpRequestException : _Request headers must contain only ASCII characters._
