Gotchas - Unicode vs. Ascii

When I get stuck trying to extract data from a web page, my final resort is to get the raw HTML and parse that (see Get Html)

     Sometimes, to aid debugging, I would save the HTML to a file so I could go back and check it manually.

     Sometimes the file write failed for no apparent reason.

It turns out that most (not all) websites are UTF-8 but QTP handles things internally in Unicode.

     But the Scripting FileSystemObject OpenTextFile default format is Ansi/Ascii.

Most of the time, you get away with it, but now and again, it blows up on you.

So when you open a file to write Unicode to, you have to remember to:

     Set oFileTo = oFsoTo.OpenTextFile("", ForWriting, True, TristateTrue)

          (where Const ForWriting = 2, TristateTrue = -1)

I also have a function that gets the file encoding here
