UTF16 Encoding Tool is a tool used to encode strings into the UTF16 format. It can convert the input string into the UTF16 encoding format, and also decode an already encoded string into the original string.

Features:

1. Input the string that needs to be encoded into the tool.

2. The tool will automatically convert the input string into the UTF16 encoding format.

3. Input the already encoded string into the tool.

4. The tool will automatically decode the input encoded string into the original string.

Use cases:

1. String encoding: During the development process, it is necessary to encode some strings into a specific format for transmission and storage. Using the UTF16 Encoding Tool can encode the string into the UTF16 format for transmission and storage between different systems.

2. String decoding: In some cases, it is necessary to decode an already encoded string into the original string. Using the UTF16 Encoding Tool can decode the already encoded string into the original string for further processing.
