BQN's strings escape double quotes by doubling them, so that the string used to start with only contains a single quote, although the output needs to have four quote characters. This also means that the source string is displayed with lots of quotes in the REPL.

```
∾2/0‿8⊏↓"∾2/0‿8⊏↓"""
        "∾2/0‿8⊏↓"""  # Source for the function, followed by a quote
       ↓              # All suffixes
   0‿8⊏               # Suffixes 0 and 8: all, and the last character
 2/                   # Copy each twice
∾                     # Join it together
```
