Run the example hereafter you will have this message :

The char "é" is in ISO-8859-1but expat doesn't like it.

The DTD contained in foo_text is an external entity.
As such it is treated separately (it does not inherit
the document entity's encoding declaration).

You need to add an XML declaration with the appriopriate
encoding to foo_text, and your program should work.
