Traditional line length research, limited to print-based text, gave a variety of results, but generally for printed text it is widely accepted that line lengths fall between 45 and 75 characters per line (cpl), though the ideal is 66 cpl (including letters and spaces). [1]
The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline.The most common versions are the en dash –, generally longer than the hyphen but shorter than the minus sign; the em dash —, longer than either the en dash or the minus sign; and the horizontal bar ―, whose length varies ...
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;
The examples of "longest words" within the "Agglutinative languages" section may be nowhere near close to the longest possible word in said language, instead a popular example of a text-heavy word. Systematic names of chemical compounds can run to hundreds of thousands of characters in length. The rules of creation of such names are commonly ...
This led to the idea that text in Chinese and other languages would take more space in UTF-8. However, text is only larger if there are more of these code points than 1-byte ASCII code points, and this rarely happens in the real-world documents due to spaces, newlines, digits, punctuation, English words, and (depending on document format) markup.
A string of seven characters. In computing and telecommunications, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language. [1] Examples of characters include letters, numerical digits, common punctuation marks
HTML (and some other modern text presentation formats) uses dynamic word wrapping which is more flexible than characters per line restriction and may produce a text block with non-rectangular shape, just like in paper typesetting. Many plain text documents still conform to 72 CPL out of tradition (e.g., RFC 678).
For example, using a superscript character for the numeral 4 is likely indistinguishable from using the standard character for a numeral 4 and then using rich text protocols to make it superscript. Such alternate rich text characters therefore create ambiguity because they appear visually the same as their plain text counterpart characters with ...
