Hi Marc,

there are some Java conversion tools available at <http://sourceforge.net/projects/dnb-conv-tools/>. For the conversion from MAB2 to UTF-8 use the following command:

>java -jar XMab2Utf8-1.9.4.jar -i file_in -o file_out

A conversion back from UTF-8 to MAB2 is not available. It would be lossy...

I´ve tried to use enc2xs with the UCM table from <https://metacpan.org/module/Encode::MAB2>, but had no success...
