Ref: https://httpwg.org/specs/rfc7230.html#header.fields field-value = *( field-content / obs-fold ) field-content = field-vchar [ 1*( SP / HTAB ) field-vchar ] field-vchar = VCHAR / obs-text - we do not accept the obsolete line folding (obs-fold) - VCHAR is 0x20 to 0x7e - obs-text is 0x80 to 0xff So we end up with !VCT_CTL || HTAB (LF) This change would be the basis for new use cases, like - a type method .valid_header - a feature flag +validate_headers which would call VRT_ValidHdr for all SetHdr calls
