Findc feature allows searches on non alphanumeric names

[nus-pe-bot]

In addc and editc, a name provided must be in alphanumeric characters. However, the findc feature does not exhibit the same behaviour, and I can provide a non alphanumeric name to search for.

This does not result in unexpected behaviour, as searching for invalid names simply does not return any contacts.

Duplicate status (if any):
