Translator not work as expected!

[cazz]

Good day!
Somehow the �bersetzung skin closely with me not.
W�RDE like to know what �bersetzung I now just need....

to the test: itheming(dot)de

Sometimes it works sometimes not out...
Often one sees what the users have written then not at all.

Or do I need a Google necessarily API v2?
If so, how exactly do I apply them.

Thank you in advance!
