Xmoji is a straightforward X11 emoji keyboard that works independently of toolkits or input methods. With features like left-clicking to insert emojis with zero-width spaces, and a search tab to find emojis by name, the tool aims to improve emoji handling for X11 applications. Unique to Xmoji is its use of X resources for appearance and rendering configuration. While still a work in progress, Xmoji is designed to be user-friendly and efficient. The tool also allows for customizations through command-line arguments and build options, making it a versatile option for emoji input on X11 systems.
