What
Control characters are invisible codes, such as the C0 and C1 ranges, that tell a terminal or program to do something instead of printing a letter. Two places in Claude Code that wrap text before passing it on used to clean such text and pass it through. They now return nothing when the text contains any control character.
Why
Text that reached Claude before may now be dropped without notice if it contains control characters.
