| /* POSIX paths in JSON via escaping which | |

| The trick is recognizing that JSON can store binary nulls in strings | |
| but nulls are the only character that can't occur in POSIX paths, | |
| so we can use it as an escape character that won't change how existing | |
| serialized paths get interpreted. | |
