Yes, I am from Switzerland, and we have some non-ASCII chars in our
language (e.g., öäü, and of course some french chars too, since
Switzerland has four languages).
I can also tell that even Chinese and Russian chars are correctly converted.

Yes, it has been tested for some time now. But since that change is only
in the TSVN trunk, not that many people are really using it yet.

Yes, and such arguments simply can't be opposed. You see, there is no
way to prove that it really works *exactly* as apr-iconv, at least not
that I know of a way.

If you read those you will see that it's not really a windows problem
but a problem with code pages. Of course it's not possible to convert
all utf8 sequences into one codepage. And windows has its own local
codepages (because they're not really standardized (is that a word?)).
And since each OS has its own local (custom) codepages, you can get into
troubles. But: as it also says there: both MultiByteToWideChar() and
WideCharToMultiByte() work just fine, and that's all we use.

Well, we could add some kind of table which maps the code-page strings
to the windows code-page defines. But since I had no need for that, I
skipped it (also because I had no intention to go through all the
trouble again to get my patch accepted).
