Description
Drupal 9 website Drupal core 9.4.11 Web Server nginx/1.20.1. PHP Version 8.0.27 site composer.lock file references "masterminds/html5": "^2.7". The relevant modules are the feeds module and the feeds tamper module.
When attempting to restore txt file assets via the feeds module an error is thrown preventing any of the import file from running. The error will not occur if the .txt has no special characters or encoding. If \22238, or <93>brackets, etc are present the feed will fail and throw an error point to mb_convert_encoding. Around 10%-20% of the assets files in my import won't run and there is no message pointing to which records have the problems until you check individually.
Previously the feeds handled this code correctly, but at some point it stopped possibly related to php 8 or server changes.
