With the default 'bytes' encoding, tokens are encoded prior to being
|
passed to the converter. This means that the output of the converter may
|
be bytes instead of unicode as expected by `read_rows`.
|
|
This test checks that outputs from the above scenario are properly decoded
|
prior to parsing by `read_rows`.

Python built-in `float` function. In a naive version of the float parser,

these strings resulted in values that were off by an ULP or two.
