Eight upper case characters with diacritics are included in International Morse Code: Ä, Á, Å, Ch, É, Ñ, Ö, and Ü. This system also includes the twenty six characters of the Latin alphabet, ten numerals, and punctuation. It was developed by Friedrich Clemens Gerke in 1848 and adopted as an international standard in 1865. Extended ASCII, an eight-bit encoding standard introduced in 1981 with the IBM PC, has 37 characters with diacritics (both upper case and lower case). "Latin-1," a slightly revised version of this character set, is still in use. Unicode UTF-16, included in Windows 2000, has many more characters with diacritics as well as an almost unlimited character set.

All major style guides advise the writer to select a widely available reference work and to follow the spellings given in this work. Now that Unicode is standard, dictionary spellings can be reproduced exactly. Older guidance that suggests dropping off technically difficult diacritics can be disregarded. ''The Chicago Manual of Style'' recommends ''The Merriam-Webster Collegiate Dictionary'', while the Associated Press recommends ''Webster’s New World College Dictionary''. Generally speaking, better known names, for example "Istanbul" or "Zurich," are spelled without diacritics, while lesser known names are spelled in the manner of the original language. Diacritics are not normally used for sports figures or for Vietnamese names. These are just rules of thumb, and each case should be checked separately in an appropriate reference work.

''The Chicago Manual of Style'' recommends ''The Merriam-Webster Collegiate Dictionary'', while the Associated Press recommends ''Webster’s New World College Dictionary''. Better known names, for example "Istanbul" or "Zurich," are often spelled without diacritics in English even though the official spelling in the local language includes them.
