In all modern character sets, the null character has a code point value of zero. In most encodings, this is translated to a single code unit with a zero value. For instance, in UTF-8 it is a single zero byte. However, in Modified UTF-8 the null character is encoded as two bytes : 0xC0,0x80. This allows the byte with the value of zero, which is ...
In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference: &name;
Using several blank lines, <br /> tags or {} will not work correctly for all display widths, and surplus blank lines are removed by a number of processes. Many infoboxes take an image, so if an image is placed there, it'll add more height that may benefit from balancing with text and other left-justified content.
These unnecessary characters usually include whitespace characters, new line characters, comments, and sometimes block delimiters, which are used to add readability to the code but are not required for it to execute. Minification reduces the size of the source code, making its transmission over a network (e.g. the Internet) more efficient.
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
A "character" may use any number of Unicode code points. [21] For instance an emoji flag character takes 8 bytes, since it is "constructed from a pair of Unicode scalar values" [22] (and those values are outside the BMP and require 4 bytes each). UTF-16 in no way assists in "counting characters" or in "measuring the width of a string".
Pressing ↵ Enter once will place a line break in the markup, but it will not show in the rendered content, except when using list markup. Markup such as bold or italics will be terminated at a line break. Blank lines within indented wikitext should not be added due to accessibility issues.
The carriage return character (CR), when sent to such a device, causes it to put the character at the edge of the paper at which writing begins (it may, or may not, also move the printing position to the next line). The line feed character (LF/NL) causes the device to put the printing position on the next line.
