# Hello,
#
# It looks like regexp with \n in [^] behaves badly if locale has
# an UTF-8 ctype.
#
# It looks like if there is \n and an range without \n, like /\n[^x\n]foo/,
# and first \n ends an even-numbered line within the string, regexp
# does not match.
#
# Please see the attached script for an demonstration.
