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). In programming
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set / Unicode code point, and uses the format: &#xhhhh; or. &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.

This method gives the HTTP server a convenient way to alter document's encoding according to content negotiation; certain HTTP ...
MouseText is a set of display characters for the Apple IIc, IIe, and IIGS that includes box-drawing characters. Encoding. On many platforms, the character shape is determined programmatically from the character code. ZX Spectrum block characters: 0x80 + topright*1 + topleft*2 + bottomright*4 + bottomleft*8; Amstrad CPC block characters:
Whitespace defines a command as a sequences of whitespace characters. For example, [Tab][Space][Space][Space] performs arithmetic addition of the top two elements on the stack. A command is written as an instruction modification parameter (IMP) followed by an operation and then any parameters. [1] IMP sequences include: Operator sequences ...

[1] UTF-8 is capable of encoding all 1,112,064 [a] valid Unicode code points using one to four one- byte (8-bit) code units.
Non-breaking space. In word processing and digital typesetting, a non-breaking space ( ), also called NBSP, required space, [1] hard space, or fixed space (in most typefaces, it is not of fixed width ), is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive ...
Figure space. A figure space or numeric space [1] is a typographic unit equal to the size of a single numerical digit. Its size can fluctuate somewhat depending on which font is being used. This is the preferred space to use in numbers. It has the same width as a digit and keeps the number together for the purpose of line breaking.
