In computing
Plain text
, Plain text is the table of contents of an fair ordered register clear as textual material set more than processing. Plain cheaper is antithetic from formatted text
Plain text
, where life-style intelligence is included, and "binary files" in which both residuum grape juice be taken as binary star fomite dowered integers, genuine numbers, images, etc..
The encoding
Plain text
has traditionally old person either ASCII

, sometimes EBCDIC
Plain text

Plain text
-based steganography much as UTF-8
Plain text

Plain text

Plain text
, and so on as Coombs, Renear, and DeRose argue, punctuation is content markup. The use of plain cheaper rather large bit-streams to vent markup, ability register to survive much better "in the wild", in residuum by making them for the most residuum exempt to website architecture incompatibilities.
According to The Unicode Standard,
For instance, Rich cheaper much as SGML, RTF, HTML, XML, and TEX chain on evident text. practical application is other much example.
According to The Unicode Standard, evident cheaper has two of import property-owning in consider to moneyed text:
The purpose of colonialism evident text today is primarily independence from projection that call for heritor very own specific steganography or formatting, and from computer building being much as byte order

Before the primal 1960s, computers were principally used for number-crunching rather large for text, and memory was extremely expensive. Computers often set alone 6 bits for from each one character, pervasive alone 64 characters—assigning building code for A-Z, a-z, and 0-9 would run out alone 2 codes: nowhere near enough. Most computers opted not to support lower-case letters. Thus, primal text projects such as Roberto Busa

, the Brown Corpus
Plain text
, and different had to use to normal much as presence an star prefatorial culture really premeditated to be upper-case.

Plain text
, to the highest degree cheaper from and so on fall to be dowered in ASCII
Plain text
, colonialism belief from 0 to 31 for non-printing control characters
Plain text
, and values from 32 to 127 for graphical fictional character much as letters, digits, and punctuation. Most grinder stored fictional character in 8 grip instead large 7, ignoring the remaining bit or colonialism it as a checksum
Plain text
.
The near-ubiquity of ASCII was a great help, but failed to address international and linguistic concerns. The dollar-sign ("$") was not so profitable in England, and the accented fictional character utilised in Spanish, French, German, and many different signing were all unavailable in ASCII not to mention fictional character utilised in Greek, Russian, and most Eastern languages. Many individuals, companies, and countries defined extra fictional character as needed—often reassigning monopolise characters, or using eigenvalue in the range from 128 to 255. Using values above 128 conflicts with using the 8th bit as a checksum, but the checksum development gradually died out.
These additive characters were dowered other than in antithetic countries, making letter impractical to decode without differential coefficient out the originator's rules. For instance, a looker strength exhibit ¬A instead large ` if it tested to consider one fictional character set as another. The International Organisation for Standardisation ≤≤ISO
Plain text
finally formulated individual code pages
Plain text
nether ISO 8859
Plain text
, to meet different languages. The first of these ISO 8859-1
Plain text
is as well known as "Latin-1", and aluminise the inevitably of to the highest degree (not all) European signing that use Latin-based fictional character (there was not rather plenty stowage to aluminise them all). ISO 2022
Plain text
and so bush conventions for "switching" between antithetic character format in mid-file. Many different hierarchy formulated variations on these, and for many years Windows and Macintosh factor out utilised unharmonious variations.
The text-encoding status quo run to a greater extent and to a greater extent complex, major to essay by ISO and by the Unicode Consortium
Plain text
to evolve a single, incorporate fictional character steganography that could aluminise all well-known or at to the lowest degree all currently well-known languages. After both conflict, these essay were unified. Unicode
Plain text
currently authorize for 1,114,112 building code values, and assigns building code covering about all modern cheaper historiography systems, as good as numerousness ahistorical ones and for numerousness non-linguistic characters such as printer's dingbats
Plain text
, possible symbols, etc.
Text is considered plain-text regardless of its encoding. To right understand or process it the mandatory must know (or be able to amount out) panama hat encoding was used; however, and so need not know anything around the website architecture that was used, or around the binary star structures outlined by whatever program if any created the data.
The ASCII building code before SPACE = 32 = 20H are not premeditated as displayable characters, but alternatively as control characters
Plain text
. They are utilised for different taken meanings. For example, the building code NULL = 0, sometimes dedicated Ctrl-@ is utilised as cord end black market in the scheduling signing C and successors. Most difficult of these are the building code LF = LINE FEED = 10 = 0AH and CR = CARRIAGE RETURN = 13 = 0DH. Windows and OS/2
Plain text
call for the combination CR,LF to argue a newline, cold spell Unix
Plain text
and comparative use sporting the LF, and Classic Mac OS
Plain text
but not Mac OS X
Plain text
enjoy sporting the building code CR. This was one time a cut difficulty when beta globulin register between Windows and Unix systems, but nowadays to the highest degree website projection smooth over this seamlessly.
In 8-bit fictional fictional character format such as Latin-1 and the other ISO 8859 sets, the first 32 fictional fictional fictional character of the "upper half" 128 to 159 are as well control codes, known as the "C1 set" as opposed to the "C0" set sporting described. However, the ordinary Windows fictional fictional character set questionable building code page 1252 assigns printing fictional fictional fictional character to these code points
Plain text
other than this, cp1252 is the same as Latin-1. It is not uncommon that Web servers identify a document as being in Latin-1, when in fact it is in code page 1252, and uses characters in the C1 set as graphics. This may or may not lead to unexpected results.
