Microsoft Text Analysis activity doesn't return appropriate response in some language except English


Microsoft Text Analysis activity doesn’t return appropriate response if I send some sentences in Japanese language via “Sentiment” and “KeyPhrases” API.

I checked the HTTP requests and found that the activity didn’t send a “language” member in “Sentiment” and “KeyPhrases” API request. I suppose it need to send a “language” member expressly in some language except English.

I’m glad if the activity would automatically use it from response of “Language” API or there would be a property for it.
