HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name.
A double dagger, or diesis, ‡ is a variant with two hilts and crossguards that usually marks a third footnote after the asterisk and dagger. [5] The triple dagger ⹋ is a variant with three crossguards and is used by medievalists to indicate another level of notation.
[8] [9] In programming languages such as Ada, [10] Fortran, [11] Perl, [12] Python [13] and Ruby, [14] a double asterisk is used, so x 2 is written as x ** 2. The plus–minus sign, ±, is used as a shorthand notation for two expressions written as one, representing one expression with a plus sign, the other with a minus sign.
In the Ada, Fortran, Perl, Python, Ruby programming languages, in some dialects of the Pascal programming language, and many others, a double asterisk is used to signify exponentiation: 5**3 is 5 3 = 125. In the Perl programming language, the asterisk is used to refer to the typeglob of all variables with a given name.
If the gap is between a colon list and an asterisk list, there is no issue, as the HTML is identical with or without the blank line. Likewise, a single-line gap between an unindented line and an indented line makes no difference. Leaving multiple lines, however, will cause the creation of an empty paragraph.
A metacharacter is a character that has a special meaning to a computer program, such as a shell interpreter or a regular expression (regex) engine.. In POSIX extended regular expressions, there are 14 metacharacters that must be escaped — preceded by a backslash (\) — in order to drop their special meaning and be treated literally inside an expression: opening and closing square brackets ...
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F.
