Frequently Asked Questions
Binary representation converts each character to its numerical code (ASCII or Unicode), then converts that number to binary (base-2) format using only 0s and 1s. For example, "A" is 65 in ASCII, which is 01000001 in binary.
ASCII supports only 128 characters (0-127), mainly English letters, digits, and basic symbols. UTF-8 supports all Unicode characters including emoji, accented letters, and characters from all languages. ASCII uses exactly 8 bits per character, while UTF-8 uses variable length.
Space separator is most readable (e.g., "01001000 01101001"). No separator creates a continuous string of 0s and 1s (useful for compact representation). Comma and dash separators can be useful for data formats that require specific delimiters.
8-bit uses 8 binary digits per character (e.g., 01001000 for "H"), suitable for ASCII and most common characters. 16-bit uses 16 binary digits, which can represent a larger range of Unicode characters including emoji and special symbols.
