New issue 3089: sqlite db with non-ascii characters in path

Scott Horowitz:

If you have a database path with non-ascii characters (e.g., "Á"), then sqlalchemy will fail with:
"unable to open database file None None"

Python's sqlite3 also exhibits this behavior. However, you can workaround this in sqlite3 by doing:

```
#!python

import sqlite3, os
os.chdir("/path/with/non/ascii/character")
conn = sqlite3.connect("file.db")
```

This does not work with sqlalchemy, however, because the create_connect_args() method in sqlalchemy\dialects\sqlite\pysqlite3.py has the following code where an absolute path is always provided to sqlite:

```
#!python

        if filename != ':memory:':
            filename = os.path.abspath(filename)

```

If this code is removed, then the workaround works as expected.

That said, it will not resolve the issue of non-ascii characters in the filename itself, just the path.
