Native API - Windows foreign letters


I am having trouble with letting foreign letters come right when I send event with the Native C++ API on Windows.

If I put it in the event like “Björn Eiríksson” then it comes all messed up on the Sentry web, and even worse if I do L"Björn Eiríksson", and if I utf8 encode it then its also messed up.

Additionally then Foreign letters in directory paths to DLLs that the web lists up are all messed up.

Is there something I might be doing wrong or is this known bug ?

Thank you
