Schema validation fails on SQL Server when we set ddl-auto=validate and use char column mapped to String

@Column(columnDefinition = "char(2)", length = 2)
 private String myColumn;

Works fine in version 5.2.10 and also works fine on H2 database with newer versions but fails on SQL Server:

org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in column [myColumn] in table [`myTable`]; found char (Types#CHAR), but expecting [[char(2)] (Types#VARCHAR)]
