[Koha] Koha 3.0 alpha - MARC-Export

[Beda Szukics]

Hello everybody

I have a problem with the marc-export function of Koha 3.0 alpha. It 
looks like it exports MARC-8 instead of Unicode.

An example:

The following record I exported from my 2.2.9-install. (and broke it 
with MarcEdit)

=LDR  00706nam a22002294u 4500
=001  001600436
=003  0
=005  20070604085600.0
=008  061222s2007\\\\sz\\\\\\\\\\\\00\\c\ger\\
=020  \\$a978-3-7643-7779-3

=600  17$aEuler, Leonhard$2SWD
=700  1\$aHeyne, Alice
=700  1\$aPini, Elena S.
=942  \\$cBUCH$k92 EUL
=952  \\$bSB$dSB$k92 EUL$p6824$u247

I imported it into my 3.0 alpha. After the search the record was 
perfectly well displayed (Birkhäuser being the "test"-word).

But when I export it the result is the following (again after a break up 
with MarcEdit, who gave an error):

=LDR  00734nam a22002414u 4500
=001  001600436
=003  0
=005  20070604085600.0

What's wrong? Koha 3.0 or did I miss some parameter-setting?
