sanitize_control_chars

Parameters

Name	Type	Description
`text`*	`str`	Untrusted text to sanitize.
`keep_newlines`	`bool`	Default:`False` When `True`, newlines survive so multiline, scrollable surfaces keep their line structure; otherwise newlines are flattened to spaces along with the other control characters.
`collapse_whitespace`	`bool`	Default:`True` When `True`, runs of whitespace are collapsed to a single space and surrounding whitespace is stripped. With `keep_newlines`, collapsing is applied per line so line breaks are preserved.
`max_length`	`int \| None`	Default:`None`

Neutralize control characters and deceptive Unicode in untrusted text.

Untrusted strings (MCP server errors, config-file contents, tool output) can carry ANSI escape sequences, other control characters, or invisible Unicode that corrupts the terminal, breaks out of a layout, or injects fake lines into logs and prompts. This first removes the invisible/bidi code points flagged by strip_dangerous_unicode, then replaces every remaining Unicode "Other" (control/format) character with a space.
