An "All Languages Keyboard" is a keyboard layout that allows users to type in any language. This type of keyboard layout typically includes characters and symbols from a wide range of languages and scripts, including Latin, Greek, Cyrillic, Chinese, Japanese, Korean, and many others. Some all languages keyboards also include support for emoji and other special characters. There are several different ways to type in multiple languages using an all languages keyboard, including switching between different keyboard layouts, using key combinations to access special characters, or using a virtual on-screen keyboard. https://all-keyboard.com/
