Wikipedia

  1. Overstrike

    In typography, overstrike is a method of printing characters that are missing from the printer's character set. The character is created by placing one character on another one — for example, overstriking "L" with "-" results in printing a "Ł" (L with stroke) character. The ASCII code supports six different diacritics. These are: grave accent, tilde, acute accent (approximated by the apostrophe), diaeresis (double quote), cedilla (comma), and circumflex accent. Each is typed by typing the preceding character, then backspace, and then the 'related character', which is `, ~, ', ", , or ^, respectively for the above-mentioned accents. With the wide adoption of Unicode (especially UTF-8, which supports a much larger number of characters in different writing systems), this technique is of little use today. However, combining characters such as diacritics are still used to depict characters which cannot be shown otherwise. Many font renderers in computer programs invent missing bold characters by overstriking the normal character with itself, slightly horizontally offset. The horizontal offset is essential since, unlike a typewriter where repeating a letter in exactly the same space will make it darker, most modern printers will not darken repeated "strikes" to the same space. Actual bold fonts are designed with some features thicker and others the same size as a regular font, so the use of this "fake bold" is considered undesirable from a typographic point of view. The character set for the APL programming language includes several characters that were printed by overstriking other characters on printing terminals such as the IBM 2741, for example the functions ⌽ and ⊖ may be used to reverse the elements of an array. WordPerfect word processing program included an overstrike functionality. Word and LibreOffice/OpenOffice do not. No known keyboard arrangement includes a function key that allows any two characters to be superimposed.

  1. Overstrike

    In typography, overstrike is a method of printing characters that are missing from the printer's character set. It was widely used around the early 1990s. The character was created by placing one character on another one — for example, overstriking "L" with "-" resulted in printing a "Ł" character. Many font renderers in computer programs invent missing bold characters by overstriking the normal character with itself, slightly horizontally offset. The horizontal offset is essential, since unlike a typewriter, where repeating a letter in exactly the same space will make it darker, most modern printers will not darken repeated "strikes" to the same space. Actual bold fonts are designed with some features thicker and others the same size as a regular font, so the use of this "fake bold" is considered undesirable from a typographic point of view; some typesetting programs, including Mac OS X's native font chooser and text renderer, go so far as to refuse to fake bold in this way.
