How it works

Each Unicode code point is written in base 2, 16, or 10 and separated from the next with a space. Reverse conversion validates every token in the selected radix, rejects values above U+10FFFF, and creates one code point per token; this is code-point notation, not UTF-8 byte encoding.

Formula
binary digits = Unicode code point written in base 2
  • Binary is padded to at least 8 digits for readable ASCII-range values but grows beyond 8 digits for larger Unicode values.
  • Text-to-code and binary are the initial choices because they match the primary text-to-binary task.

When to use this

Unicode inspection checks U+ values, HTML and XML debugging checks numeric character references, and radix exercises compare “A” as decimal 65, hexadecimal 41, and binary 01000001.

Edge cases

  • 😀 is the single code point U+1F600 and therefore needs more than eight binary digits; padding is a minimum width, not a byte boundary.
  • 👨‍👩‍👧‍👦 contains several emoji code points joined by U+200D, so one visible family glyph produces multiple numeric tokens.
  • 11000011 10101001 represents the UTF-8 bytes for é, but entering those as binary code points produces two characters because UTF-8 byte decoding is outside this conversion.
