TTY stands for "TeleTYpe" or "TeleTYpewriter" and is also known as Teleprinter or Teletype. In the 1954 short film Stamp Day for Superman, typewriter art was a feature of the plot. Typewriter art was also called keyboard art. ![]() The oldest known preserved example of typewriter art is a picture of a butterfly made in 1898 by Flora Stacey. Since 1867 typewriters have been used for creating visual art. 3.3.4 "Amiga"/"Oldskool" style ASCII art. ![]() 3.3.3 "Block ASCII" / "High ASCII" style ASCII art on the IBM PC.3.3 Styles of the computer underground text art scene.The ASCII art phenomenon continues to exist in the social and mobile web, even when constrained to only 140 unicode characters, as exhibited by Twitter channels such as and many others, tagged as #TwitterArt and #140art. ASCII art was also used in early e-mail when images could not be embedded. Also, to mark divisions between different print jobs from different users, bulk printers often used ASCII art to print large banners, making the division easier to spot so that the results could be more easily separated by a computer operator or clerk. One of the main reasons ASCII art was born was because early printers often lacked graphics ability and thus characters were used in place of graphic marks. "Studies in Perception I" by Ken Knowlton and Leon Harmon from 1966 shows some examples of their early ASCII art. ![]() foo is sorted before -foo) the only exception is when they're the only character in a filename – they'll then be after ,Ī careful examination of the above table will reveal that + and = are not in the order they would be in if File Explorer sorting was done strictly by Unicode Value.Among the oldest known examples of ASCII art are the creations by computer-art pioneer Kenneth Knowlton from around 1966, who was working for Bell Labs at the time. ² File Explorer ignores ' and - when sorting unless there's a direct conflict with another filename, in which case, the opposed filename takes precedence (e.g. ¹ File Explorer's sort order does not differentiate between uppercase and lowercase letters in filenames Listed in File Explorer's ascending sort order UnicodeĠ-9 0030 – 0039 digit zero through digit nineĪ-z¹ 0041 – 005A, capital letter A through Z The following table of ASCII characters allowed in filenames (showing the characters, their Unicode values and a description of the character) is arranged in the sort order used by Windows 10 File Explorer. However, for Windows 10 File Explorer characters in the Basic Latin block (ASCII characters), this is not strictly true. The other answers state that symbol characters are sorted by Unicode value. The simple answer is that none of the symbols are sorted after the letters (not taking into account the special way ' and - is handled, see below). The answers provided in this discussion, while interesting, are somewhat esoteric. The lowest rule observed is Unicode order, so items within a type-language group are ordered by Unicode value (U+xxxx). The following order seems to apply for this: The second level of grouping is by culture/language. ![]() Therefore, any symbol from any language comes before any number from any language, while any letter from any language appears after all symbols and numbers. The highest level of grouping is by type in the following order. This means that the first rule applied is the last rule observed, while the last rule applied is the first or topmost rule observed.ģ.) Sort on Type (Symbol, Number, Letter) The ordering of older rules becomes nested under the ordering of newer rules. Ultimately, what you have are sorting rules that are applied in a certain order, in turn, this produces an observed order. It's worth noting that there are really two ways of looking at this. Hebrew (ordered by Unicode value (U+xxxx))Īrabic (ordered by Unicode value (U+xxxx)) Greek (ordered by Unicode value (U+xxxx))Ĭyrillic (ordered by Unicode value (U+xxxx)) Latin (ordered by Unicode value (U+xxxx)) I did some testing and the overall ordering seems to be as follows.
