Bug report
Bug description:
from urllib.request import urlopen
with urlopen("file:\\C:/temp/test.txt") as response:
print(response.read())
That works in python 313 but fails in 314
Just checking if it's intended change? This resulted failure when upgrading 313->314
Same url works in webbrowser, Firefox, Edge, in Windows 11
CPython versions tested on:
3.14
Operating systems tested on:
Windows
