Please use verbatim blocks ({{{ }}}) and always preview your ticket before submitting it: your message is hardly readable.

Is your locale properly configured on your machine?

utf8@euro is quite unusual: utf8 (unicode) already defined the euro symbol. It's quite common to use @euro for ISO-8859 page code, but it looks like unusual with UTF-8.

This is not a blocker issue anyway: simply use another locale (de_DE.utf8 should do it)
