Hi, the PyImport_ExecCodeModuleWithPathnames documentation states that the char* strings should be encoded in UTF-8. But looking at the Python C code, it is aparent that PyUnicode_DecodeFSDefault is used to convert these string, so the documentation need to state the the string should be encoded as in the default of the local filesystem. https://docs.python.org/3/c-api/import.html#c.PyImport_ExecCodeModuleWithPat... regards, Florian P.S. I ran into this because I passed in UTF-8 and the __file__ attribute of the imported modules was wrong afterwards. -- ------------------------------------------------------------------------ Florian Link MeVisLab Tel.: +49-421-22495 579 Fax: +49-421-22495 899 www.mevis.de / www.mevislab.de MeVis Medical Solutions AG Caroline-Herschel-Str. 1 28359 Bremen Germany Trade Registry: Bremen HRB 23791 VAT ID: DE250659412 Executive Board: Marcus Kirchhoff (Chairman), Dr. Robert Hannemann Chairperson of Supervisory Board: Kimberley E.
