##### .XCompose Definitions #####

# Hint: For testing:
#  ibus-daemon -r -d
#     detach xterm+ ; exit # after replacing ibus-daemon
#  xxx ibus restart # breaks everything, no XCompose at all

# Start by loading standard system definitions from:
# /usr/share/X11/locale/en_US.UTF-8/Compose
include "%S/en_US.UTF-8/Compose"

## Next, define some symbols that are neither math nor Greek
## one shortcut is already defined in system-wide control file:
## <Multi_key> <s> <s>      : "ß" # system predefined esszett (sharp s)
<Multi_key> <s> <z>         : "ß" # another way of writing esszett (sharp s)

## Also eth and capital Eth are already defined:
## <Multi_key> <d> <h>              	: "ð"   eth # LATIN SMALL LETTER ETH
## Also thorn and capital Thorn:
## <Multi_key> <t> <h>         : "þ"   thorn # LATIN SMALL LETTER THORN


## Math-Related Symbols:
