any ascii input codice_1 to codice_15 excluding space codice_2 resets the encoder to codice_8. because the above-mentioned values cover line end code points codice_18 and codice_19 "as is" (codice_20), the encoder is in a known state at the begin of each line. the corruption of a single byte therefore affects at most one line. for comparison, the corruption of a single byte in utf-8 affects at most one code point, for scsu it can affect the entire document.
