This list: http://msdn.microsoft.com/en-us/library/ms812845.aspx - it looks to be an outdated MSDN contents page, or something very much like, so I assume it's at lesat fairly authoritative. (I got the link here, which I found via google: http://microsoft.public.platformsdk.mslayerforunicode.narkive.com/QbsrNDDh/list-of-functions-handled-by-mslu)

And under G, GetCharABCWidthsFloat is indeed missing.

I suspect the page is a bit outdated, because some of the links are broken. (And also, of course, because it deal with Windows '9x...)

Thanks,
