_FTP_FilePut and Unicode file names

[Synchro]

I'm having trouble using Chinese Unicode file names with _FTP_FilePut().

I can read the file names correctly with FileFindNextFile(), but they are munged on the remote machine when sent via _FTP_FilePut().

I tried converting the file names to UTF-8 using _WinAPI_WideCharToMultiByte(), but that didn't help either.

I can transfer the file names correctly using FileZilla if I force it to use UTF-8.

Has anyone had any success using Unicode file names with _FTP_FilePut()?

I tried modifying _FTP_FilePut() to send a UTF-8 string via FtpPutFileA() and to send wide strings via FtpPutFileEx(), to no avail.

I'm beginning to suspect that DllCall() doesn't pass wide strings correctly.

Has anyone successfully passed wide strings to DllCall()?

DLLCall has no bug with wstr. The problem should be FTPPutFile. I think, it converts the unicode to ascii before sending the string to the server. You should try to use FtpOpenFileA with an UTF-8 encoded string and InternetWriteFile. You could modify the _FTP_ProgressUpload for that.

It looks like updating to v3.3.6.1 fixed the problem.

I can now send Chinese file names via _FTP_FilePut() if I convert them to UTF-8 using _WinAPI_WideCharToMultiByte().
