The Unicode character encoding standard features check marks that computer users can use in modern operating systems, software applications and programming languages.

The Unicode designation for the check mark is U+2713. To enter it in Microsoft Windows, hold down the Alt key, press the plus key on the numeric keypad and tap in the hexadecimal value "2713." This method may require enabling a setting in the Windows Registry. Alternately, users can type "2713" and press Alt+X in applications such as Microsoft Word and WordPad to display a check mark. In C, C++ and Java, programmers must type "u2713" (including the quotation marks) in the source code to display a check mark.
Unicode also offers other variations of the check mark. U+2714 is a check mark in bold type, whereas U+2611 is a ballot box with a check mark. The radical sign or square root symbol as a check mark uses the Unicode designation is U+221A.
A character encoding is only shown properly if the software supports it. If a software can't properly display a Unicode character, it may replace the character with blanks and question marks.Learn more about Keyboard
