Wikimedia Commons has media related to Text mode box drawing. Sample diagrams made out of the standard box-drawing characters, using a monospaced font: On many platforms, the character shape is determined programmatically from the character code.Д x80 + topright*1 + topleft*2 + bottomright*4 + bottomleft*8Д x80 + topleft*1 + topright*2 + bottomleft*4 + bottomright*8Д xA0 + topleft*1 + topright*2 + middleleft*4 + middleright*8 + bottomleft*16 + bottomright*64ДOS linedraw characters are not ordered in any programmatic manner, and calculating a particular character shape needs to use a look-up table.

Some recent embedded systems also use proprietary character sets, usually extensions to ISO 8859 character sets, which include box-drawing characters or other special symbols.

These characters were added to the Unicode standard in Version 13.

A character cell is divided in 2Г—3 regions, and 2 6В =В 64 code positions are allocated for all possible combinations of pixels. The World System Teletext (WST) uses pixel-drawing characters for some graphics. MouseText is a set of display characters for the Apple IIc, IIe, and IIgs that includes box-drawing characters.

The CP/M Plus character set used on various Amstrad computers of the CPC, PCW and Spectrum families included a rich set of line-drawing characters as well: The Amstrad CPC character set also has soft characters defined by default as block and line drawing characters. The BBC Master and later Acorn computers have the soft font by default defined with line drawing characters. Control characters were used to switch between regular text and box drawing. The BBC Micro could utilise the Teletext 7-bit character set, which had 128 box-drawing characters, whose code points were shared with the regular alphanumeric and punctuation characters.

The Sinclair ZX80, ZX81 and Spectrum included a set of text semigraphics with block elements and dithering patterns. Some of these sets, such as Commodore's PETSCII, include box-drawing symbols with no corresponding Unicode character. Many microcomputers of the 1970s and 1980s had their own proprietary character sets, which also included box-drawing characters. Modern Unix terminal emulators use Unicode and thus have access to the line-drawing characters listed above. On some terminals, these characters are not available at all, and the complexity of the escape sequences discouraged their use, so often only ASCII characters that approximate box-drawing characters are used, such as -В ( hyphen-minus), |В ( vertical bar), _ ( underscore), = ( equal sign) and +В ( plus sign) in a kind of ASCII art fashion. The escape sequence EscВ (В 0 switched the codes for lower-case ASCII letters to draw this set, and the sequence EscВ (В B switched back:ДЄ Bash script that displays all of the semigraphic characters: On many Unix systems and early dial-up bulletin board systems the only common standard for box-drawing characters was the VT100 alternate character set (see also: DEC Special Graphics).

Some OEM DOS computers supported other character sets, for example the Hewlett-Packard HP 110В / HP Portable and HP 110 PlusВ / HP Portable Plus, where in a modified version of the character set box-drawing characters were added in reserved areas of their normal HPВ Roman-8 character set. Note: The non-double characters are the thin (light) characters (U+2500, U+2502), not the bold (heavy) characters (U+2501, U+2503). Their number is further limited to 22 on those code pages that replace the 18 characters that combine single and double lines with other, usually alphabetic, characters (such as code page 850): This subset of the Unicode box-drawing characters is thus far more popular and likely to be rendered correctly:

The hardware code page of the original IBM PC supplied the following box-drawing characters, in what DOS now calls code page 437. ^ Grey areas indicate non-assigned code points In version 13.0, Unicode was extended with another block containing many graphics characters, Symbols for Legacy Computing, which includes a few box-drawing characters and other symbols used by obsolete operating systems (mostly from the 1980s): The Block Elements Unicode block includes shading characters. The image below is provided as quick reference for these symbols on systems that are unable to display them directly: Official Unicode Consortium code chart (PDF) In many Unicode fonts only the subset that is also available in the IBM PC character set (see below) will exist, due to it being defined as part of the WGL4 character set. Unicode includes 128 such characters in the Box Drawing block.
