Unicode only specifies semantics for U+0009—U+000D, U+001C—U+001F, and U+0085 (the ASCII format effectors except for {{ctrl|BS}}, plus the ASCII information separators and the C1 {{ctrl|NEL}} and the ASCII information separators). The rest of the control characters are transparent to Unicode and their meanings are left to higher-level protocols, although interpretation as defined in ISO/IEC 6429 is suggested as a default.<ref name="unicode-23-1">{{cite book |url=https://www.unicode.org/versions/Unicode12.0.0/ch23.pdf#page=3 |title=23.1: Control Codes |work=The Unicode Standard |edition=12.0.0 |date=2019 |author=Unicode Consortium |author-link=Unicode Consortium |isbn=978-1-936213-22-1 |pages=868–870}}</ref> Furthermore, certain specialised higher-level protocols, such as transcoded [[Teletext]], may include a [[Teletext character set#Control characters|different interpretation]] of the entire C0 control code range.<ref>{{cite web |url=https://corp.unicode.org/pipermail/unicode/2020-October/009120.html |title=Teletext separated mosaic graphics |work=Unicode Mailing List Archive |last=Ewell |first=Doug |date=2020-10-16 |publisher=[[Unicode Consortium]] |quotation=I reiterate that it was UTC {{bracket|[[Unicode Technical Committee]]}} and Script Ad Hoc who provided the guidance to the group writing the [[Symbols for Legacy Computing]] proposal (and there is a second on the way) that 0x00 through 0x1F in the original teletext set should map to U+0000 through U+001F when converting to Unicode.}}</ref>
