UTF-16 (16-bit Unicode Transformation Format) is a character encoding capable of encoding all 1,112,064 valid code points of Unicode (in fact this number of code points is dictated by the design of UTF-16). The encoding is variable-length, as code points are encoded with one or two 16-bit code units. UTF-16 arose from an earlier obsolete fixed ...
Comparison of Unicode encodings. This article compares Unicode encodings in two types of environments: 8-bit clean environments, and environments that forbid the use of byte values with the high bit set. Originally, such prohibitions allowed for links that used only seven data bits, but they remain in some standards and so some standard ...
Intel HEX. Intel hexadecimal object file format, Intel hex format or Intellec Hex is a file format that conveys binary information in ASCII text form, [10] making it possible to store on non-binary media such as paper tape, punch cards, etc., to display on text terminals or be printed on line-oriented printers.

ASCII (/ ˈæskiː / ⓘ ASS-kee), [3]: 6 an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.
Unicode, formally The Unicode Standard, [note 1] is a text encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 of the standard [A] defines 154 998 characters and 168 scripts [3] used in various ordinary, literary, academic, and ...
Cyrillic script in Unicode. As of Unicode version 16.0, Cyrillic script is encoded across several blocks: The characters in the range U+0400–U+045F are basically the characters from ISO 8859-5 moved upward by 864 positions. The next characters in the Cyrillic block, range U+0460–U+0489, are historical letters, some of which are still used ...
