Security Fix(es): * Developer environment: Unicode's bidirectional (BiDi) override characters can cause trojan source attacks (CVE-2021-42574) The following changes were introduced in clang in order to facilitate detection of BiDi Unicode characters: clang-tidy now finds identifiers that contain Unicode characters with right-to-left direction, which can be confusing as they may change the understanding of a whole statement. For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
