WKWebView upload file which name contains Chinese character results in garbled code

I am working on a Mac app, just a simple web application encapsulated in WKWebView.

Here is the code when I tring to upload a file which name contains special character: 

-(void)webView:(WKWebView *)webView runOpenPanelWithParameters:(WKOpenPanelParameters *)parameters initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(NSArray<NSURL *> * _Nullable))completionHandler
{
     DEBUG_FUNC(@"");

     NSOpenPanel* openDlg = [NSOpenPanel openPanel];
    [openDlg setCanChooseFiles:YES];
    [openDlg setCanChooseDirectories:NO];
    [openDlg setPrompt:NSLocalizedString(@"Choose", nil)];
    openDlg.allowsMultipleSelection = YES;

    if ( [openDlg runModal] == NSOKButton ) 
    {
        if (completionHandler)
        {
            completionHandler([openDlg URLs]);
        }
    }  
}

When I was using WebView, this way can work, so it should not be a web problem.

But since the project used WKWebView,
for example: file "证书.p12" would be changed to "è¯ä¹¦.p12" after uploaded via WKWebView. Anyone know how to solve it?
Thanks!

there are some small flaws in your code (like you don't invoke the handler after cancel), also it is outdated...

- (void)webView:(WKWebView *)webView runOpenPanelWithParameters:(WKOpenPanelParameters *)parameters initiatedByFrame:(WKFrameInfo *)frame completionHandler:(nonnull void (^)(NSArray<NSURL *> * _Nullable))completionHandler{

    NSOpenPanel * openDialog = [NSOpenPanel openPanel];
    [openDialog setCanChooseFiles:YES];
    [openDialog setCanChooseDirectories:NO];
    openDialog.allowsMultipleSelection = NO;

    [openDialog beginSheetModalForWindow:self.view.window completionHandler:^(NSModalResponse result) {
        if (result == NSModalResponseOK) {
            completionHandler([openDialog URLs]);
        } else {
            completionHandler(nil);
        }
    }];
