Can it have characters like '/'?

All examples are from SQlite 3.5.9 running on Linux.

If you surround the column name in double quotes, you can:

> CREATE TABLE test_forward ( /test_column INTEGER );
SQL error: near "/": syntax error
> CREATE TABLE test_forward ("/test_column" INTEGER );
> INSERT INTO test_forward("/test_column") VALUES (1);
> SELECT test_forward."/test_column" from test_forward;
1

That said, you probably shouldn't do this.
