It is not reasonable to expect that the write_xml function would
silently drop data by default.
If you want invalid data to be removed, you'll have to do this yourself
prior to calling the function.

This signature of write_xml doesn't actually do anything encoding-wise,
it outputs your data as-is, and marks the data as being the encoding you

It might be more sensible to set up the encoding correctly though, or to
convert your data to the right encoding.
There is another overload of write_xml that can imbue a locale when
writing the data, which can be used for transparent transcoding.
