# This patch will allow slrn to override the charset value "us-ascii"
# declared in postings with the value of the fallback charset. This
# might be useful to handle google postings I sometimes ran across,
# which claimed to be "us-ascii" but had 8 bit characters inside. This
# can be done by adding 

#  set usascii_override 1

# to the .slrnrc.
