gucharmap

gucharmap [OPTION...]

--block=BLOCKNAME
    Opens the character map directly to the specified Unicode block. For example, to view mathematical symbols, you might use --block="Mathematical Operators".

--character=CHARACTER_CODEPOINT
    Opens the character map and highlights the specified character code point. The code point should be provided in hexadecimal format, optionally prefixed with 'U+'. For instance, --character=U+20AC for the Euro sign or --character=00A9 for the copyright symbol.

--version
    Displays the version information of gucharmap and then exits immediately.

--help
    Shows a comprehensive list of all available command-line options for gucharmap and then exits.

--display=DISPLAY
    Specifies the X display to use. This is a common option for graphical applications running in an X environment, allowing the application to be displayed on a different screen or remote display.

--sync
    Makes X calls synchronous. While potentially useful for debugging purposes, this option can significantly slow down the application's performance.

--g-fatal-warnings
    Causes all warnings generated by the application to be treated as fatal errors, leading to the immediate termination of the application upon encountering a warning. This is primarily useful for developers during debugging.

gucharmap is the official GNOME character map application, providing a user-friendly graphical interface to browse, search, and insert Unicode characters.

It serves as an essential tool for users needing to access special characters, symbols, or characters from various languages that are not readily available on standard keyboards. The application allows users to navigate through different Unicode blocks, view detailed properties of each character (such as its Unicode name, code point, and UTF-8 encoding), and copy selected characters directly to the clipboard for use in other applications. gucharmap also supports searching for characters by name or code point, making it efficient to locate specific symbols quickly.

As an integral part of the GNOME desktop environment, gucharmap integrates seamlessly, offering a robust and intuitive solution for Unicode character management and insertion.

gucharmap is a graphical application built with GTK and requires a running X server or Wayland compositor to function. It cannot be used from a purely command-line interface without a display environment.

While it supports a vast array of Unicode characters, its primary function is display and selection; it does not offer advanced font management or character design capabilities.

Being part of the GNOME desktop environment, it might have additional dependencies if installed on a system without a full GNOME setup.

gucharmap is designed to support the latest or near-latest versions of the Unicode Standard. This ensures that users can access and utilize characters from the ever-expanding range of scripts and symbols defined by Unicode. The application's interface organizes characters logically by Unicode blocks, making navigation intuitive.

As a native GNOME application, gucharmap is tightly integrated with other GNOME components and GTK-based applications. Characters copied from gucharmap are placed onto the system clipboard and can be pasted effortlessly into any application that supports text input, enhancing productivity for users working with diverse character sets.

gucharmap has been a fundamental utility of the GNOME desktop environment since its early inception. Developed to provide users with an accessible way to browse and insert Unicode characters, its core functionality has remained consistent. Its evolution has focused on enhancing usability, keeping pace with updates to the Unicode Standard to ensure comprehensive character coverage, and integrating seamlessly with the broader GNOME ecosystem.
