When converting to UTF8, can you specify that you are using Latin-9 
(ISO-8859-15), instead of Latin-1? Latin-9 is equivalent to Latin-1 plus 
the Euro sign, instead of the generic currency sign, since Latin-1 
predates the Euro.

In that case, it would be:

    Euro_Sign : constant Character := Character'Val (164);

This is from Ada.Characters.Latin_9, provided by GNAT (not in the 
standard). Not sure, buy maybe you could type the Euro sign in the 
source code with the keyboard, since the representation is the same.

Another option is to use ASCII only (with some encoding for umlauts and 
Euro sign) and then apply localization for the strings that must be 
"translated" to proper German.
