Eight characters with diacritics are included in International Morse Code: Ä, Á, Å, Ch (a Czech digraph), É, Ñ, Ö, and Ü. This encoding method, which includes only capital letters, was developed by Friedrich Clemens Gerke in 1848 and was adopted as an international standard in 1865.

In the early 1900s, teletype displaced Morse code for most purposes. Teletype was encoded using Baudot, a five-bit code developed in 1870 that includes only capital letters and no diacritics. Baudot, in turn, was displaced by ASCII, a seven-bit code developed in 1963 that includes both upper and lower cased letters. IBM introduced Extended ASCII, an eight-bit encoding standard, with the original PC in 1981. This set includes 37 characters with diacritics. Latin-1, a slightly revised version of the IBM character set, was adopted as an international standard in 1987.<ref>[http://www.unicode.org/charts/PDF/U0080.pdf Controls and Latin-1 Supplement], Unicode, Inc.</ref>

Unicode, implemented by the Windows operating system since 2000, includes Latin-1 as well as a comprehensive collection of Nordic, Eastern European, and even Asian characters. Unicode characters can be up to four bytes long. This allows for over 1.1 million characters to be encoded, although only 113,000 codepoints have been assigned so far.<ref>Cunningham, Andrew, "[http://arstechnica.com/gadgets/2014/06/unicode-7-0-introduces-2834-new-characters-including-250-emoji/ Unicode 7.0 introduces 2,834 new characters, including 250 emoji]", ''Ars Technica'', June 17, 2014</ref>
