Overstrike

Updated: 11/13/2018 by Computer Hope

Overstrikes with diacritical marksAn overstrike is a technique used in typesetting to create special characters by printing over another more commonly-used character. These special characters typically have diacritic marks to denote a different spoken pronunciation.

Note: The term "overstrike" should not be confused with strikethrough, a style of text that has a line through it to indicate that is has changed or been removed. In HTML, strikethrough text looks like this:

Using overstrikes in HTML

Characters with overstrikes can be represented in HTML by adding the decimal or hexadecimal HTML entity immediately after the character to be overstruck. For example, the acute accent, which looks like a diagonal line moving up and right above a letter, is represented by the HTML entity ́ (in decimal) or &x0301; (in hexadecimal). If this HTML code is used immediately after a character which can be overstruck, the accent will be printed over that character. If not used immediately after an overstrikable character, the accent will be printed by itself.

For example:

HTML displays as
O O
́ ́
Ó
́ ́
Ó
