    buffer - the data buffer.
    
    Returns:
    
    the decoded integer as big endian.
  - unicodeUString
```

```
    Decode a unicode (VARCHAR) string from ByteBuf with unsigned short length.
    
    Parameters:
    
    buffer - the data buffer.
    
    Returns:
    
    the decoded String.
  - unicodeBString
```
public static String unicodeBString(io.netty.buffer.ByteBuf buffer)
```
    Decode a unicode (VARCHAR) string from ByteBuf with byte length.
