--TEST--
Test Always Encrypted in Windows by comparing fetched values from fields of fixed and variable widths
--DESCRIPTION--
See Internal issue 2824 for details. In the plaintext case, the padding is added by SQL, not the driver. For AE, the motivation was to facilitate matching between char and varchar types, that is, a deterministic encryption of char(10) with “abcd” to match varchar(10 with “abcd”.
