GNOME Character Map, formerly and internally known as Gucharmap, is a free and open-source software Unicode character map program, being one of the GNOME Core Applications. This program allows characters to be displayed by Unicode block or script type. It includes brief descriptions of related characters and occasionally meanings of the character in question. Gucharmap can also be used to input or enter characters. The search functionality allows the use of several search methods, including by Unicode name or code point of the character. It is built on the GTK toolkit and can be run on any platform supported by GTK. A number of text programs use Gucharmap for character input.
