The HikaMarket order export works the same than the HikaShop order export.
The order product name is not altered, so the HTML tag added for options is not striped.
Regarding the "umlauts", I do have the felling that the issue is more regarding the UTF-8 encoding. Please perform a test with a CSV export and open the file with a text editor where you can see/set the encoding.

The order export customization is the same for HikaShop and HikaMarket.
It is possible to use "view overrides" or " plugin trigger".
The two forum threads are talking about the two solutions ; but you can find more threads in this forum with more example and maybe some PHP code which will suits your needs.
The idea behind the view override is to allow you to add some PHP code to remove content in the " $row " array, so these entries won't be exported.
As you can see in the view, 3 entries are modified before the "writeLine($row)" to improve the display of some date variables.
