The Internet Extensions for Win32, a.k.a. WinINet.dll, has been around for a long time.
Does it support Unicode? Yes, it does -- a bunch of "W" functions, though many of them seem to convert the strings from Unicode.
Does it support Unicode on Win9x? No, it does not (as far as I know).
Does MSLU (the Microsoft Layer for Unicode on Win9x Systems) support the functions in it? No, it does not.
So imagine my surprise when I noticed the following text in the help topic in the Platform SDK for FtpPutFile (similar text in most of the other WinINet functions):
Implemented as FtpPutFileW (Unicode) and FtpPutFileA (ANSI). Note that Unicode support on Windows Me/98/95 requires Microsoft Layer for Unicode.
So just to dispell any lurking rumors, MSLU support has not been expanded to WinINet.dll and there are no plans for such an expansion.
I mean, after all, even extended support for Windows 98 and Windows Me ends on July 11th of this year!
I'll mention this to the SDK folks, hopefully this post will be obsolete soon enough....

"though many of them seem to convert the strings from Unicode."
Which might mean that it already supports Win9x without MSLU anyway.

I disassembled it in IDA Pro and there is also some A wrappers that convert and call the W version in wininet too, even on Win9x. In any case, all this means that the W functions in wininet.dll are already available on Win9x without MSLU, at least the IE 6 SP1 version!

Why on earth would you still be running Win9x? :-)

I am not, I was just disassembling DLLs.
