…acters This fixes sanitize_uri_values where it wouldn't correctly filter uris with disallowed protocols if the scheme had a unicode invisible character in it. Now the code strips all non-ASCII characters from the uri before parsing and testing the scheme. GHSA-8rfp-98v4-mmr6
This is the last release of Bleach. There will be no future releases including for security fixes. Thank you all for using and contributing to Bleach!
