Hi devcrp,

Thanks for the repo code. I was able to reproduce the issue. I was using a .net core application and you were using .net framework. It works fine in .net core, but is broken in .net framework. The issue will be fixed in the next release which will hopefully happen soon., For now you can do the following workaround.

        public static async Task<string> Insert(Person person)
        {
            using (var cosmosClient = new CosmosClient(new CosmosConfiguration(ENDPOINT, KEY).UseCustomJsonSerializer(new CustomJsonSerializer())))
            {
                var container = cosmosClient.Databases[DB].Containers[CONTAINER];
                var response = await container.Items.CreateItemAsync(person.id, person);
                return JsonConvert.SerializeObject(person);
            }
        }

        public static async Task<Person> Get(string id)
        {
            using (var cosmosClient = new CosmosClient(new CosmosConfiguration(ENDPOINT, KEY).UseCustomJsonSerializer(new CustomJsonSerializer())))
            {
                var container = cosmosClient.Databases[DB].Containers[CONTAINER];
                CosmosItemResponse<Person> result = await container.Items.ReadItemAsync<Person>(id, id: id);
                return result.Resource;
            }
        }

        /// <summary>
        /// The default Cosmos JSON serializer
        /// </summary>
        internal class CustomJsonSerializer : CosmosJsonSerializer
        {
            private static readonly JsonSerializer Serializer = new JsonSerializer();
            private static readonly Encoding DefaultEncoding = new UTF8Encoding(false, true);

            public override T FromStream<T>(Stream stream)
            {
                using (stream)
                {
                    if (typeof(Stream).IsAssignableFrom(typeof(T)))
                    {
                        return (T)(object)(stream);
                    }

                    using (StreamReader sr = new StreamReader(stream))
                    {
                        using (JsonTextReader jsonTextReader = new JsonTextReader(sr))
                        {
                            return CustomJsonSerializer.Serializer.Deserialize<T>(jsonTextReader);
                        }
                    }
                }
            }

            public override Stream ToStream<T>(T input)
            {
                MemoryStream streamPayload = new MemoryStream();
                using (StreamWriter streamWriter = new StreamWriter(streamPayload, encoding: CustomJsonSerializer.DefaultEncoding, bufferSize: 1024, leaveOpen: true))
                {
                    using (JsonWriter writer = new JsonTextWriter(streamWriter))
                    {
                        writer.Formatting = Newtonsoft.Json.Formatting.None;
                        CustomJsonSerializer.Serializer.Serialize(writer, input);
                        writer.Flush();
                        streamWriter.Flush();
                    }
                }

                streamPayload.Position = 0;
                return streamPayload;
            }
        }

Hi devcrp,

I was not able to repo the issue. I created the item via the SDK and viewed it in the portal data explorer and it appears fine.

dynamic test = new { id = "newid", name = "Román", AccountNumber = "1234890" };
var response = await container.Items.CreateItemAsync(test.AccountNumber, test);

What are you using to view the inserted item? When you read the item back via the SDK is it still correct? Can you provide a link to a github repository with the repo?

Hi j82w,

Here's the test project where I can reproduce the issue: https://github.com/devcrp/CosmosDBvsDiacritics
In this case I'm using the cosmosDB emulator to test it locally, but the result is the same when using the CosmosDB in the Azure server.

Also, here's where I'm viewing the inserted item

And this is the container's config in case it helps

That did it, thank you!!
