Pangram

A pangram or holoalphabetic sentence is a sentence using every letter of a given alphabet at least once. Pangrams have been used to display typefaces, test equipment, and develop skills in handwriting, calligraphy, and typing.
The best-known English pangram is "The quick brown fox jumps over the lazy dog". It has been used since at least the late 19th century and was used by Western Union to test Telex/TWX data communication equipment for accuracy and reliability. Pangrams like this are now used by a number of computer programs to display computer typefaces.
Short pangrams in English are more difficult to devise and tend to use uncommon words and unnatural sentences. Longer pangrams afford more opportunity for humor, cleverness, or thoughtfulness.
The following are examples of pangrams that are shorter than "The quick brown fox jumps over the lazy dog" (which has 35 letters) and use standard written English without abbreviations or proper nouns:
A perfect pangram contains every letter of the alphabet only once and can be considered an anagram of the alphabet. The only perfect pangrams of the English alphabet that are known use abbreviations or other non-dictionary words, such as "Blowzy night-frumps vex'd Jack Q." or "Mr. Jock, TV quiz PhD, bags few lynx." or they include words so obscure that the phrase is challenging to understand, such as "Cwm fjord-bank glyphs vext quiz", in which cwm is a loan word from the Welsh language meaning an amphitheatre-like glaciated depression, vext is an uncommon way to spell vexed, and quiz is used in an archaic sense to mean a puzzling or eccentric person. It means that symbols in the bowl-like depression on the edge of a long steep sea inlet confused an eccentric person.
Other writing systems may present more options: The Iroha is a well-known perfect pangram of the Japanese syllabary, while the Hanacaraka is a perfect pangram for the Javanese script and is commonly used to order its letters in sequence.
Whereas the English language uses all 26 letters of the Latin alphabet in native and naturalized words, many other languages using the same alphabet do not. Pangram writers in these languages are forced to choose between only using those letters found in native words or incorporating exotic loanwords into their pangrams. Some words, such as the Gaelic-derived whisk(e)y, which has been borrowed by many languages and uses the letters k, w and y, are a frequent fixture of many foreign pangrams.
There are also languages that use other Latin characters that do not appear in the traditional 26 letters of the Latin alphabet. This differs further from English pangrams, with letters such as ç, ä, and š.
Non-Latin alphabetic or phonetic scripts such as Greek, Armenian, and others can also have pangrams. In some writing systems, exactly what counts as a distinct symbol can be debated. For example, many languages have accents or other diacritics, but one might count "é" and "e" as the same for pangrams. A similar problem arises for older English orthography that includes the long s ("ſ").
("Mr.Sangkhaphant Hengpithakfang - an elderly man who earns a living by selling bottles - was arrested for prosecution by police because he stole Lady Chatchada Chansamat's watch.") contains all the letters in the Thai alphabet, both obsolete and non-obsolete.
Logographic scripts, or writing systems such as Chinese that do not use an alphabet but are composed principally of logograms, cannot produce pangrams in a literal sense (or at least, not pangrams of reasonable size). The total number of signs is large and imprecisely defined, so producing a text with every possible sign is practically impossible. However, various analogies to pangrams are feasible, including traditional pangrams in a romanization.
In Japanese, although typical orthography uses kanji (logograms), pangrams can be made using every kana, or syllabic character. The Iroha is a classic example of a perfect pangram in non-Latin script.
In Chinese, the Thousand Character Classic is a 1000-character poem in which each character is used exactly once; however, it does not include all Chinese characters. The single character 永 (permanence) incorporates all the basic strokes used to write Chinese characters, using each stroke exactly once, as described in the Eight Principles of Yong.
Among abugida scripts, an example of a perfect pangram is the Hanacaraka (hana caraka; data sawala; padha jayanya; maga bathanga) of the Javanese script, which is used to write the Javanese language in Indonesia.
A self-enumerating pangram is a pangrammatic autogram, or a sentence that inventories its own letters, each of which occurs at least once. The first example was produced by Rudy Kousbroek, a Dutch journalist and essayist, who publicly challenged Lee Sallows, a British recreational mathematician resident in the Netherlands, to produce an English translation of his Dutch pangram. In the sequel, Sallows built an electronic "pangram machine", that performed a systematic search among millions of candidate solutions. The machine was successful in identifying the following 'magic' translation:
Chris Patuzzo was able to reduce the problem of finding a self-enumerating pangram to the boolean satisfiability problem. He did this by using a made-to-order hardware description language as a stepping stone and then applied the Tseytin transformation to the resulting chip.
The pangram "The quick brown fox jumps over the lazy dog", and the search for a shorter pangram, are the cornerstone of the plot of the novel Ella Minnow Pea by Mark Dunn. The search successfully comes to an end when the phrase "Pack my box with five dozen liquor jugs" is discovered (which has only 6 duplicated vowels).
The scientific paper Cneoridium dumosum (Nuttall) Hooker F. Collected March 26, 1960, at an Elevation of about 1450 Meters on Cerro Quemazón, 15 Miles South of Bahía de Los Angeles, Baja California, México, Apparently for a Southeastward Range Extension of Some 140 Miles has a pangrammatic title, seemingly by pure chance.
