How to get Unicode string from redis cache using StackExchange.Redis in c#?

Question

I am using StackExchange.Redis library to work with redis. I have set Unicode string value as below.

db.StringSet(key,"धन्यवाद");

And I am trying to get Unicode string using

db.StringGet(key);

But getting ????? instead of Unicode string. Redis stores Unicode string value in below format.

\xe0\xa4\xa7\xe0\xa4\xa8\xe0\xa5\x8d\xe0\xa4\xaf\xe0\xa4\xb5\xe0\xa4\xbe\xe0\xa4\xa6

@Nico getting (error) ERR unknown command '--raw' on redis cli. Have you tried this?!!! — dharmesh parmar, Jul 20 '17 at 21:25
I test your code, it works fine and i can get the right string and cmd like 'redis-cli --raw mget key' works fine on my pc, too. I think its a enviroment problem, what is your redis version? If it still does not work, just check the second answer, decode that string. — NicoXiang, Jul 21 '17 at 01:02

RedisValue has an implicit cast operator of type string. It encodes it as an UTF-8 byte array before sending it. If you have your string in Unicode you should obtain the bytes by yourself.

byte[] data = Encoding.Unicode.GetBytes(value);
db.StringSet(key, data);
...
data = db.StringGet(key);
value = Encoding.Unicode.GetString(data);
