TextIOWrapper‽ converting files to strings in Python - Python Morsels
February 5, 2024 - Unfortunately, that just gives us back a generic string representation saying the object we've converted is an _io.TextIOWrapper object. ... Well, reading a file isn't an entirely trivial operation. In fact, when you read from a file, if you read the same file a second time, you'll see that it's empty: >>> file.read() 'This is an example text-based file.\nIt existed before we read it.\n' >>> file.read() ''

It turns out you just need to wrap your io.BytesIO in io.BufferedReader which exists on both Python 2 and Python 3.
import io
reader = io.BufferedReader(io.BytesIO("Lorem ipsum".encode("utf-8")))
wrapper = io.TextIOWrapper(reader)
wrapper.read() # returns Lorem ipsum
This answer originally suggested using os.pipe, but the read-side of the pipe would have to be wrapped in io.BufferedReader on Python 2 anyway to work, so this solution is simpler and avoids allocating a pipe.

Buffering refers to the technique of gathering some amount of bytes before writing it to the destination. TextIOWrapper gathers the contents up to the occurrence of a new line character before making a call to flush. Buffering can be turned-off if write_through is enabled. The example uses a BytesIO object as the underlying buffer.
