This allows sending unicode symbols using `X(<unicode>)` in your keymap. Codes
up to 0xFFFFF are supported, including emojis. But you need to maintain a
separate mapping table in your keymap file.
up to 0xFFFFFFFF are supported, including emojis. You will need to maintain
a separate mapping table in your keymap file.
Known limitations:
- Under Mac OS, only codes up to 0xFFFF are supported.
- Under Linux ibus, only codes up to 0xFFFFF are supported (but anything important is still under this limit for now).
Characters out of range supported by the OS will be ignored.
