### `void llhttp_set_lenient_header_value_relaxed(llhttp_t* parser, int enabled)`
401+
402+
Enables/disables relaxed handling of control characters in header values.
403+
404+
Normally `llhttp` would error when header values contain characters not in the valid set (HTAB, SP, VCHAR, OBS_TEXT). With
405+
this flag, control characters (except for NULL, CR & LF) will be accepted in header values.
406+
407+
This does not create any known security issue, but does allow content considered 'invalid' by
408+
[RFC 9110](https://www.rfc-editor.org/rfc/rfc9110#name-field-values) and so should be avoided by default.
