[Petal] XIncludes and charsets

[Chris Croome]

Hi

Say you have a load of Petal templates, all UTF-8 and then someone opens
one for editing in a not-so-clever editor which finds no non-ASCII
characters and decided that it's a ASCII file. The someone addes an
eacute and the not-so-clever editor decided to save the file back as
Latin-1.

This file that is now Latin-1 is XIncluded into another UTF-8 file...
things start to go horribly wrong...!

Perhaps Petal should check for a XML PI with the charset for each file
it XIncludes and use encode if needed, ie something like this:

  <?xml version="1.0" encoding="UTF-8" ?> [1]

In any case (Petal checking for charset conflicts or not) a PI like the
one above should probably be removed, if present, when a file is
XIncluded.
