generate-text-emphasis-style-property-010-tests.sh

#!/usr/bin/env bash

# This script generates tests text-emphasis-style-property-010* except
# 010Cn. The tests generated cover all characters listed in the unicode
# data file which should not have emphasis mark specified in the spec.
# This script downloads UnicodeData.txt from the website of the Unicode
# Consortium and extract the characters form that file. It requires
# python (either 2.5+ or 3.x), awk, and wget to work. Only test files
# are generated by this script. It also outputs a list of all tests it
# generated in the format of Mozilla reftest.list to the stdout. Other
# information has been redirected to the stderr.
