In a mailfolderfile I see the following attachment:

<from mail>
  Content-Type: image/pjpeg;
	name="=?UTF-8?B?c2FtZW4gbWV0IEFuZHLDqSBraWprZW4gbmFhciBQYXNjYWwuanBn?="
  content-transfer-encoding: base64
  Content-Disposition: attachment;
	filename="=?UTF-8?B?c2FtZW4gbWV0IEFuZHLDqSBraWprZW4gbmFhciBQYXNjYWwuanBn?="
<\from mail>

This has to do with an utf-8 encoded filename. But also it looks as yet more encoded.

The filename decodes to: samen met Andr� kijken naar Pascal.jpg

Is c2FtZW4gbWV0IEFuZHLDqSBraWprZW4gbmFhciBQYXNjYWwuanBn the piece that represents this?

I googled a bit and read:

<quote>
 > Is there any method or API to convert a file from UTF-8 to Ascii or Ansi ?

Load the contents of the file, translate it to Unicode with
MultiByteToWideChar(CP_UTF8, ...), and convert it to your required
code page with WideCharToMultiByte.
</quote>

In my bcb5 I cannot find these functions.

How to tackle this ?

Hans.
