Bug report

Bug description:

_pyrepl.readline._ReadlineWrapper.get_line_buffer should return astr, not abytes object, becausereadline.get_line_buffer also returns anstr, not abytes.

this has very little effect in CPython, but in PyPy it causes various problem, because we don't have areadline module at all, and use_pyrepl.readline instead.

I'm working on a PR.

CPython versions tested on:

3.13, CPython main branch

Operating systems tested on:
