Describe the bug

This code snippet has a bug: it converts %2F to /, which causes the signature to fail. aiohttp/client.py 547 line

try:
    url = self._build_url(str_or_url)
except ValueError as e:
    raise InvalidUrlClientError(str_or_url) from e

To Reproduce

x-signature=rX7AnN6H6BGSzbXpbUQsY%2FXCC2w%3D => x-signature=rX7AnN6H6BGSzbXpbUQsY/XCC2w%3D

Expected behavior

x-signature=rX7AnN6H6BGSzbXpbUQsY%2FXCC2w%3D => x-signature=rX7AnN6H6BGSzbXpbUQsY%2FXCC2w%3D
