Review comment:
Consider using a `Map` instead to keep the respective `dataSource` and
`invalidChars` elements paired correctly. For example:
```java
Map<String, String> invalidCharToDataSourceName = ImmutableMap.of(
"\\t", "\tab\t",
"\\r", "\rcarriage\return\r",
"\\n", "\nnew\nline\n"
);
// iterate over map entries
```
