```python
db[""people""].insert({""name"": ""Mary""}, pk=""name"").m2m(
""people"", [{""name"": ""Michael""}, {""name"": ""Suzy""}], m2m_table=""parent_child"", pk=""name""

[people_id_2] TEXT REFERENCES [people]([name]),

One thought would be to support something like this:
```python
rows = db[""otherdb.tablename""].rows_where()
```

That database has 3141 rows in it:

I converted that `csv` file to utf-8 like so:

If we know the file size in bytes AND we know the character encoding, can we change `UpdateWrapper` to update the number of bytes-per-character instead?
I don't think so: I can't see a way of definitively saying ""for this encoding the number of bytes per character is X"" - and in fact I'm pretty sure that question doesn't even make sense since variable-length encodings exist.
