Description

Alexey Grigoryev (Migrated from SEC-2530) said:

BasicAuthenticationFilter has hard coded char set UTF-8.
But according to RFC2616, RFC2617 it should be iso-8859-1 or detected with mime format which does not happen too.

Research direction

Start by locating BasicAuthenticationFilter and inspect where its Basic Authentication credentials are decoded. Read the referenced RFC2616 and RFC2617 guidance and the linked discussion, then determine the expected charset behavior; done means the filter no longer unconditionally uses UTF-8 and has regression coverage for the agreed behavior.
