Character Map is a utility included with Microsoft Windows operating systems and is used to view the characters in any installed font, to check what keyboard input (Alt code) is used to enter those characters, and to copy characters to the clipboard in lieu of typing them. The tool is usually useful for entering special characters. It can be opened via the command line or Run Command dialog using the 'charmap' command.
The Advanced view check box can be used to inspect the character sets in a font according to different encodings (code pages), including Unicode code ranges, to locate particular characters by their Unicode code point and to search for characters by their Unicode name. For Unicode fonts, the characters can be grouped by their Unicode subrange. Although the Unicode standard already extends character field to plane 16 and many fonts e.g. MingLiU-ExtB begin to support higher ranges, this tool still only supports code points on plane 0 (between U+0000 and U+FFFF). Additionally, it does not display certain characters in that range for reasons unexplained. On Microsoft Windows XP, Windows Vista, and Windows 7, the utility is in All Programs → Accessories → System Tools → Character Map in the Start Menu. Beginning with Windows Vista, the user can also type the name of the utility in the Start Menu search box.
