Viewing: prompt_special_chars

# Utility function to set up some special characters
# used by prompts.
#
# These used to be defined to characters found in particular
# character sets (e.g. IBM852) which now aren't widely used.
# We still provide them in that form if the current character
# set isn't UTF-8.  We could in principle use iconv if available.
