{{Short description|Character encoding standard}}
{{lipu pona
|blurb='''[[Special:MyLanguage/ASCII|ASCII]]''' is a character encoding standard that features 95 printable characters, limited to the basic Latin alphabet and symbols on the United States keyboard layout. This character set is the basis of several [[Special:MyLanguage/Toki Pona|Toki Pona]] projects, due to its availability compared to specialized keyboards and [[Special:MyLanguage/input method|input method]]s.

'''ASCII''' ('''American Standard Code for Information Interchange''') is a character encoding standard updated from 1963 to 1986, and a precursor to [[Special:MyLanguage/Unicode|Unicode]].
ASCII features only 128 codepoints, many of which are {{w|control character}}s, and its 94 {{w|printable character}}s are limited to the {{w|ISO basic Latin alphabet|basic Latin alphabet}} (the 26 letters also comprising the {{w|English alphabet}}) and {{w|Typographical symbol|symbols}} on the {{w|British and American keyboards|United States keyboard layout}}. This character set is the basis of several [[Special:MyLanguage/Toki Pona|Toki Pona]] projects, due to its availability compared to specialized keyboards and [[Special:MyLanguage/input method|input method]]s.

Many [[Special:MyLanguage/font|font]]s for original Toki Pona writing systems include a feature called '''ASCII transcription''',<ref>{{cite web|url=//docs.google.com/spreadsheets/d/1xwgTAxwgn4ZAc4DBnHte0cqta1aaxe112Wh1rv9w5Yk/preview|title={{tok|nimi Linku}}|author=|username=|date=|website=Google Sheets|publisher=|access-date=2024-01-17|quote=}}</ref> where a run of characters typed in {{tp|[[Special:MyLanguage/sitelen Lasina|sitelen Lasina]]}} is visually substituted with a single glyph. This simulates the effects of an {{abbr|IME|input method editor}} without the need to install [[Special:MyLanguage/software|software]] beyond the font, but unlike these, it does not actually replace the underlying text. Other ASCII characters are commonly used for additional features in the writing system or font, such as the hyphen (-) being used for {{tp|sitelen pona}} [[Special:MyLanguage/combined glyph|combined glyph]]s.

[[File:Word default no ligatures.tiff|thumb|180px|<translate>''ASCII transcription'' works like automatic Latin ligatures, where multiple glyphs are visually substituted with one.</translate>]]
<translate>
This feature uses {{w|OpenType}} {{w|Ligature (writing)|ligatures}}. It works in the same way that some Latin-script fonts convert the letters <code>ffi</code> into a ligature that <em>looks</em> like the single glyph <code>ffi</code>, but is actually still 3 underlying characters.
