Dear support,

I tried to upload a file whose name contains accented characters.
What I get is an object with a name like this:
If I change the PerformPost function call replacing the Filename parameter with URLEncode(Filename) expression then the file name is like the original but with accented characters replaced by the "%xx%xx" format.
Can this be solved in some way?

Best Regards.
Paolo Righi.

Try to encode filenames with UTF8 yourself before uploading, then they won't be converted.

Hi Eugene,

thank you for your answer.
In the meanwhile I found a working solution.
I changed the TElHTTPSClient.EncodeFieldValue to convert to UTF8 this way:

function TElHTTPSClient.EncodeFieldValue(const Value: string; const Charset : string): string;
if not NeedsEncoding then
Result := Value
ConvertUTF16toUTF8(Value, Tmp, lenientConversion, false); <<
Result := StringOfBytes(Tmp); <<
Exit; <<
{$ifdef SB_ANSI_VCL}

What do you think?

Best regards.
Paolo Righi.

Altering the source code can lead to unpredictable bugs in other scenarios.

Unfortunately it's not clear from your messages, what (unicode or non-unicode) strings you manipulate in this case, and, consequently, it's not clear, why (and if correctly) the name is converted.

Sincerely yours
Eugene Mayevski
