Wrong decoding of json "\u"

[nivekz]

• Product and API: aliyun-java-sdk-kms 2.15.0 & JsonReader class
• Platform: java
• Mininum Code:

The aliyun api (KMS) returned "&" as "\u0026". The aliyun-java-sdk-kms library calls JsonReader of aliyun-java-sdk-core to decode. But it simply ignores the '\', resulting in a "u0026".

We expect that the sdk decoder should return either "&", or "\u0026".
