Unicode only specifies semantics for {{tt|U+0009—U+000D}}, {{tt|U+001C—U+001F}}, and {{tt|U+0085}} (the ASCII format effectors except for {{ctrl|BS}}, plus the ASCII information separators and the C1 {{ctrl|NEL}}). The rest of the "Cc" control codes 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 bookweb |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>

== Interlinear annotation ==
Three formatting characters provide support for [[RubyInterlinear textgloss|interlinear annotation]] ({{unichar|FFF9|INTERLINEAR ANNOTATION ANCHOR}}, {{unichar|FFFA|INTERLINEAR ANNOTATION SEPARATOR}}, {{unichar|FFFB|INTERLINEAR ANNOTATION TERMINATOR}}). This may be used for providing notes that would typically be displayed between the lines of other text. Unicode considers such annotation to be rich text and recommends using other protocols for such annotation. The W3C [[Ruby character#Ruby markup|Ruby markup]] recommendation is an example of an alternate protocol supporting more advanced interlinear annotation.
