# We test our translations by taking the original untranslated string
# (e.g. msgid) and prepend a prefix character and then append a suffix
# character. The test consists of asserting that the first character in the
# translated string is the prefix, the last character in the translated string
# is the suffix and the everything between the first and last character exactly
# matches the original msgid.
#
# We use unicode characters not in the ascii character set for the prefix and
# suffix to enhance the test. To make reading the translated string easier the
# prefix is the unicode right pointing arrow and the suffix left pointing arrow,
# thus the translated string looks like the original string enclosed in
# arrows. In ASCII art the string "foo" would render as:
# -->foo<--
#
# Unicode right pointing arrow: u'\u2192', utf-8 = '\xe2\x86\x92'
# Unicode left pointing arrow:  u'\u2190', utf-8 = '\xe2\x86\x90'
#
# The sed command below performs the prefix and suffix substitution.
#
# When msginit is invoked with an English target locale it copies the msgid
# into the msgstr. This is an undocumented feature of msginit. Otherwise the
# msgstr will be set to the empty string (i.e. untranslated). We depend on
# the msgid being copied to the msgstr.
