3-Second Blueprint (English)

  1. ASCII maps 128 characters to 1 byte each, while Unicode maps human graphemes to one or more code points.
  2. UTF-32 uses a fixed 4 bytes per code point, whereas UTF-8 encodes each code point in 1 to 4 bytes.
  3. Decoding bytes with the wrong scheme causes mojibake, and accurate string ops require grapheme awareness.

3-Sekunden-Fazit (Deutsch)

  1. ASCII nutzt 1 Byte für 128 Zeichen; Unicode ordnet sichtbare Grapheme einem oder mehreren Codepoints zu.
  2. UTF-32 belegt fest 4 Bytes pro Codepoint, während UTF-8 variabel 1 bis 4 Bytes pro Codepoint nutzt.
  3. Falsche Dekodierung erzeugt Zeichensalat (Mojibake); präzise String-Logik muss Grapheme beachten.
