mbc-unicode-input

Uses rofi to show a character selection string, with metadata. The characters are loaded from "$HOME/.local/share/mbc-unicode-input/symbols.json".

The selected character is sent as virtual keyboard input using wtype.

Usage

Simply add your desired characters to "$HOME/.local/share/mbc-unicode-input/symbols.json" and run

mbc-unicode-input

An example symbols.json file is:
