# 20210819 bkw:
# - updated to match debian's patchlevel 9.
# - add a few more ligatures.

# Note to self: don't try to update this for Unicode standard 13.0.0.
# It'll compile and run, but the code assumes the codepoints will fit
# in an unsigned short (16 bits), which is no longer true in the new
# standard.
