Description of your pull request and other information

Current implementation of SIP002 URI Scheme parser produces wrong output for a URI with spaces in its fragment section.

Expected Behavior

Given URI ss://[email protected]:8888/?plugin=obfs-local%3bobfs%3dhttp%3bobfs-host%3dgoogle.com#example-server+1, a Server with remark example-server 1 is created.

Current Behavior

Given URI ss://[email protected]:8888/?plugin=obfs-local%3bobfs%3dhttp%3bobfs-host%3dgoogle.com#example-server+1, a Server with remark example-server+1 is created.

Note

Current behavior was also observed in other SIP002 implementations, such as Shadowrocket. This fix may break potential compatibility with these clients.

+1 Looks good to me, but someone else must approve.

Thank you @bdbai
It is okay. The remark text should have no impact on server connections. Unless some of the 3rd party subscription updater would check the remarks strictly.
