What is Decimal (ASCII/Unicode) Encoding?

Every character you type — letters, digits, punctuation, and even emojis — is assigned a unique number called a code point in the Unicode standard. "Decimal encoding" simply means representing each character by its decimal (base-10) code point value.

For example:

  • A → 65
  • a → 97
  • Space → 32
  • € → 8364

This is commonly used in HTML entities (A), programming, and data representation contexts.

Frequently Asked Questions

ASCII covers the first 128 code points (0–127), which represent basic English characters. Unicode extends this to over 1 million code points, covering every character and symbol used by all languages worldwide.

Yes. The decoder automatically splits by spaces, commas, dashes, and newlines, so it handles most common formats you might encounter.

Valid Unicode code points range from 0 to 1,114,111. If a value exceeds this, the tool will report it as invalid and halt the conversion.
