Unicode

Unicode is an encoding method that converts byte data to Unicode escape sequences, using \uXXXX format to represent non-ASCII characters. dongle supports standard and streaming Unicode encoding, implemented based on strconv.QuoteToASCII.

Encoding Data

Input Data

// Input string
encoder := dongle.Encode.FromString("你好世界").ByUnicode()

// Input byte slice
encoder := dongle.Encode.FromBytes([]byte("你好世界")).ByUnicode()

// Input file stream
file, _ := os.Open("test.txt")
encoder := dongle.Encode.FromFile(file).ByUnicode()

// Check encoding error
if encoder.Error != nil {
	fmt.Printf("Encoding error: %v\n", encoder.Error)
	return
}

Output Data

// Output string
encoder.ToString() // \u4f60\u597d\u4e16\u754c
// Output byte slice
encoder.ToBytes()  // []byte("\u4f60\u597d\u4e16\u754c")

Decoding Data

Input Data

// Input string
decoder := dongle.Decode.FromString("\u4f60\u597d\u4e16\u754c").ByUnicode()

// Input byte slice
decoder := dongle.Decode.FromBytes([]byte("\u4f60\u597d\u4e16\u754c")).ByUnicode()

// Input file stream
file, _ := os.Open("test.txt")
decoder := dongle.Decode.FromFile(file).ByUnicode()

// Check decoding error
if decoder.Error != nil {
	fmt.Printf("Decoding error: %v\n", decoder.Error)
	return
}

Output Data

// Output string
decoder.ToString() // 你好世界
// Output byte slice
decoder.ToBytes()  // []byte("你好世界")
