This rule is triggered when the symbols used in the document for fenced code blocks do not match the configured code fence style:

```ruby
# Fenced code
```

~~~ruby
# Fenced code
~~~

To fix this issue, use the configured code fence style throughout the document:

```ruby
# Fenced code
```

```ruby
# Fenced code
```

The configured list style can be a specific symbol to use (backtick, tilde), or can require that usage be consistent within the document.

Rationale: Consistent formatting makes it easier to understand a document.
