The character breakdown table is fantastic for understanding what changed. I use this to teach encoding concepts to my team.

❓ FAQ
How is text converted to binary?+
Each character is looked up by its ASCII (or Unicode) code point. That decimal number is then converted to base 2 (binary) and padded to 8 bits with leading zeros. "H" = ASCII 72 = binary 01001000.
What separator should I use?+
Use space-separated binary for human readability and compatibility with most binary-to-text tools. Continuous binary (no spaces) is compact but requires knowing the group size to decode. Newline-separated is useful for tables.
Can I convert Unicode characters beyond ASCII?+
Yes. Characters with code points above 127 (emoji, accented letters, CJK characters) are converted using their UTF-16 code unit, which may be larger than 8 bits. For proper Unicode binary, use the charCodeAt() value.
Why are binary groups 8 bits?+
8 bits = 1 byte = the standard unit of data storage. ASCII characters fit in 7 bits, but 8-bit groups are used for consistency and to support extended ASCII (128–255). Modern text encoding (UTF-8) uses 1–4 bytes per character.
How long is binary for a paragraph of text?+
Each character becomes an 8-bit group (8 characters) plus a separator. A 100-character paragraph becomes ~900 characters of binary (100 × 8 bits + 99 spaces). Binary is verbose for text but essential in computing and communications.
