"\000" meaning in Translingual

{
  "etymology_text": "From the fact that the C programming language states that a character escape sequence may consist of a maximum of three octal digits; if the shorter sequence \\0 is followed by an octal digit which is intended to represent the next character, then \\000 is required to prevent that digit from being interpreted as part of the escape sequence instead. For example, \\0 followed by 1 would be interpreted as the escape sequence \\01, whereas \\0001 is interpreted as \\000 followed by the digit 1.",
