Test gettext translation
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<--"
