Subject create collation for locale de_DE@collation=phonebook
Author Dr. Boris Neubert

with firebird 2.5 and the full icuxx30.dll libraries from the icu website I
can create collations for locale xx_YY like that:

create collation unicode_dede_ci
for utf8
from unicode
case insensitive

According to the manual the xx_YY form is the only one permissible form for
the LOCALE option.

Nonetheless I would like to use the phone book collation
de_DE@collation=phonebook. Is there a way to achieve this in the current or
in an upcoming release? I could not figure it out and a No would at least
stop me from trying.
