When the following is true and when Always Encrypted is used:

  • sendStringParametersAsUnicode=true
  • Inserting a string against a non-unicode column
  • UTF-8 collation is used
  • Server version is >= 15

The driver will safely insert the string into the non-unicode column. In all other cases, the driver will throw an error indicating a potential data loss if the insert is to be followed through.
