Editing Bracket (section)

===Quine corners ⌜⌝ and half brackets ⸤ ⸥ or ⸢ ⸣<span class="anchor" id="Quine corners and half brackets"></span>===
The Quine corners {{char|⌜}} and {{char|⌝}} have at least two uses in [[mathematical logic]]: either as [[quasi-quotation]], a generalization of quotation marks, or to denote the [[Gödel number]] of the enclosed [[Expression (mathematics)|expression]].

Half brackets are used in English to mark added text, such as in translations: "Bill saw ⸤her⸥".

In editions of [[papyrology|papyrological]] texts, half brackets, ⸤ and ⸥ or ⸢ and ⸣, enclose text which is lacking in the papyrus due to damage, but can be restored by virtue of another source, such as an ancient quotation of the text transmitted by the papyrus.<ref>M.L. West (1973) ''Textual Criticism and Editorial Technique'' (Stuttgart) 81.</ref> For example, [[Callimachus]] ''Iambus'' 1.2 reads: ἐκ τῶν ὅκου βοῦν κολλύ⸤βου π⸥ιπρήσκουσιν. A hole in the papyrus has obliterated βου π, but these letters are supplied by an ancient commentary on the poem. Second intermittent sources can be between ⸢ and ⸣. Quine corners are sometimes used instead of half brackets.<ref name="Unicode Miscellaneous Technical" />
