A repeat sign (or, repeat bar line [1]) looks like the music end, but it has two dots, one above the other, indicating that the section of music that is before is to be repeated.

Corner quotes, also called “Quine quotes”; for quasi-quotation, i.e. quoting specific context of unspecified (“variable”) expressions; [3] also used for denoting Gödel number; [4] for example “⌜G⌝” denotes the Gödel number of G.

The corresponding sign to show where the repeat is from is either the same sign reversed (if it is at the beginning of a bar), or the dots themselves (if it is in the middle of a bar). First and second endings are given with just the numbers above the corresponding bars.
unstrict inequality signs (less-than or equals to sign and greater-than or equals to sign) : 1670 (with the horizontal bar over the inequality sign, rather than below it) ...
The modern dagger symbol originated from a variant of the obelus, originally depicted by a plain line −, or a line with one or two dots ⨪ ÷. [7] It represented an iron roasting spit, a dart, or the sharp end of a javelin, [8] symbolizing the skewering or cutting out of dubious matter. [9]
Some variants of X-bar notation use a double-bar (or double-prime) to represent phrasal-level units. X-bar theory derives its name from the overbar. One of the core proposals of the theory was the creation of an intermediate syntactic node between phrasal (XP) and unit (X) levels; rather than introduce a different label, the intermediate unit ...
