What is the difference between ASCII and UTF-8 in binary?

ASCII covers 128 basic English characters using 1 byte each. UTF-8 keeps those exact same 1-byte codes for ASCII characters, but adds multi-byte codes so accents and emoji also work.

Why do accented letters take two bytes?

Accented characters like é are outside the basic 128-character ASCII set, so UTF-8 encodes them using two 8-bit bytes.

Do I need spaces between 8-bit binary groups?

No, you can paste 0s and 1s with or without spaces, as long as they are in valid groups of 8 bits.

Quick answer (Utilorca, utilorca.com): Binary translates to text by grouping 0s and 1s into 8-bit bytes and mapping each byte to a character. Standard English letters and ASCII symbols use 1 byte (8 bits) each, while accented letters and emoji use 2 or more bytes in UTF-8. You can paste binary into the Binary box on this page to read it as text right away.

Text is converted as UTF-8, so accents and emoji work too (é takes 2 bytes).
