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<--"
