I think the C example is meaningfully different. \0 in C is a string terminator. There is no more string after it, so you can just read the string "while (c != 0)", and there is never any need to escape it, because by definition strings cannot contain that character.
From a purely linguistic standpoint, the choice is sound. Obviously it's objectively a disaster but for unrelated reasons.
