Because a character’s Unicode code point is usually given in hexadecimal with a prefixed "U+", the hexadecimal code is arguably more convenient. Of course, when a name exists, a named reference (e.g., — for an em dash) is usually more convenient (and more easily recognized) than either numerical code.
In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation. Reasons for using a naming convention (as opposed to allowing programmers to choose any character sequence) include the ...
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 numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
When Citation Style 1 and Citation Style 2 templates contain |asin=, a test is done to see if the ASIN identifier contains ten upper-case alphanumeric characters without punctuation or spaces and that if the first character is numeric, that the ASIN conforms to the rules for a ten-digit ISBN.
special characters that are not available in the limited character set are stored in the form of a multi-character code; there are usually two or three equivalent representations, e.g. for the character € the named character reference € and the decimal character reference € and the hexadecimal character reference €. The edit ...
The duplicate code base doubles the time required to implement changes which may be desired across both products; this increases time-to-market for such changes, and may, in fact, wipe out any time gains achieved by branching the code in the first place. Similar to above, the alternative to a copy-and-paste approach would be a modularized approach:
Typography is the art and technique of setting written subject matter in type using a combination of typeface styles, point sizes, line lengths, line leading, character spacing, and word spacing to produce typeset artwork in physical or digital form. The same block of text set with line-height 1.5 is easier to read: Typography is the art and technique of setting written subject matter in type ...
Different people read articles in different ways. Some people start at the top and read each word until the end. Others read the first paragraph and scan through the article's body for other interesting information, looking especially at pictures and captions.
