Select with coalesce operator on field non unicode string should not append N

See original GitHub issue

I’m doing a simple select using the coalesce operator with non unicode string and the generated SQL has the appended N.

Steps to reproduce

context.Contract.Select(x => x.Description ?? "-").FirstOrDefault()
// Mapping
entity.Property(e => e.Description)
	.HasColumnName("DESCRIPTION")
	.HasColumnType("VARCHAR2(100)")
	.IsUnicode(false);

Got this query

SELECT COALESCE("x"."DESCRIPTION", N'-')
FROM "MYDB"."CONTRACT" "x"
FETCH FIRST 1 ROWS ONLY

With your test case, I see the SQL with the N character generated for the second COALESCE expression now. I’ve filed the bug 31388650 to track this issue. We’ll have a developer review the bug and fix it.

@alexkeh, you’re right. It’s working when putting the .IsUnicode(False). It works with 2.2.6 but not with 2.1.14 (lts). I was mixing the versions in my tests. Thank you for your time
