| As the post above points out, this would either work fine or
| cause an error, because of the quotes -- it's not actually SQL
| injection.
|
| In theory, a system could have an actual vulnerability but if
| it does it would mean it's also going to fail on _any_ name

| vulnerable to such attacks. Fixing them isn't something
| Companies House can do. The joke Bobby Tables company name
| that was registered deliberately wasn't actually a
| functioning SQL injection. If someone does try to register a
| name containing a real one, it seems like a good idea for
| Companies House to be able to reject it on those grounds.
| This is just giving them that ability, as part of a larger
| ability to reject names that are designed to mislead or
