• Principles of Text Format Conversion

  Encoding and Decoding Concepts

  When computers store and transmit text, they need to convert character data into numerical representations. This process is called Character Encoding. Each character is assigned a specific code value, allowing computers to interpret and process text efficiently.

  Conversely, the process of converting encoded data back to its original text form is called Decoding. Since the converted data is stored in a specific encoding format, using the correct decoding method is essential for accurate retrieval.

  Major Encoding Methods

  1. UTF-8 (8-bit Unicode Transformation Format)

  - The most widely used encoding format, utilizing variable-length encoding (1-4 bytes) to represent all Unicode characters.

  - English letters and numbers are stored in 1 byte, while complex characters such as Korean require 3 bytes.

  2. HEX (Hexadecimal Encoding)

  - Converts each character's byte value into hexadecimal representation.

  - Example: "A" → "41", "a" → "61"

  3. Base64 and Base64url

  - A method for converting binary data into ASCII characters.

  - Base64url is a modified version of Base64 designed for safe usage in URLs.

  - Example: "hello" → "aGVsbG8="

  4. Latin1 (ISO-8859-1)

  - A single-byte character encoding supporting European languages.

  - Includes ASCII characters and some special European symbols.

  5. UTF-16 (16-bit Unicode Transformation Format)

  - Represents all Unicode characters using 2-byte (16-bit) encoding.

  - Includes two variations: UTF-16BE (Big Endian) and UTF-16LE (Little Endian).

  6. Binary (Binary Encoding)

  - Converts characters into 8-bit binary representations.

  - Example: "A" → "01000001"

  7. Octal (Octal Encoding)

  - Converts characters into octal (base-8) format.

  - Example: "A" → "101"

  Conversion Process Explanation

  1. The user enters text in the input field.

  2. The text is transformed into byte data according to the selected input encoding format.

  3. The byte data is then converted into a new format according to the selected output encoding format.

  4. The transformed result is displayed in the output field.

  Practical Applications of Text Conversion

  Security and Encryption: Useful for securely storing or transmitting data using Base64 or HEX encoding.

  File Format Conversion: Ensures text compatibility across different systems through UTF-8 ↔ UTF-16 conversions.

  Programming: HEX or Binary conversions help handle binary data in various software applications.
