Message:

Feeds: Avoid fatal error with empty blog_charset value.

After the SimplePie library was updated to version 1.8.0 in [59141], an edge case has been discovered where a fatal error can encountered if the blog_charset option is missing or empty.

In fetch_feed(), this option is retrieved using get_option() instead of get_bloginfo( ‘charset’ ). The latter will detect this scenario and apply a default value of UTF-8 and is already used interchangeably throughout Core. This switches to get_bloginfo( ‘charset’ ) instead to prevent this edge case.

Props david.binda, davidbaumwald, SergeyBiryukov, sabernhardt, azaozz, peterwilsoncc.
Fixes #62354.
