What is state of the art: Unicode file names on Windows

VTK-9 can read non-Ascii filenames in any version of Windows. Simply provide the filename as a utf8 encoded string.

@lassoan In VTK-9 the code page setting is irrelevant and not required.

For VTK9 library the application code page does not matter, but for the application it still does. Since in an application you need to use C runtime and other APIs, not just VTK (for example to get the filename from a command-line argument, console input, or GUI), you still need to set the application’s code page to UTF8 to avoid manual conversions between various string encodings.

@albert.liu

UINT activeCodePage = GetACP();
I trace this line in my project, the activeCodePage is 936

This means that you don’t use UTF8 code page. You either need to convert the filename from “simplified Chinese” (CP936) to UTF8 before you pass it to VTK; or change your application manifest to use UTF8 code page (because then you can already get the filename as UTF8).
