What
Before sending a request to the model, Claude Code scans it for broken Unicode, such as half of a two-part character with its other half missing. If that scan itself fails, Claude Code now logs an error saying what happened. It then runs the scan again without its record of tool descriptions already known to be clean.
Why
This rare failure can now be traced, and the request still gets checked.
