Erroneous character encoding in xml declaration of gml files created by ogr2ogr

[peter.rushforth@…]

When reading data files containing accented characters and writing
gml files, the data is incorrectly characterised as utf-8 in the
xml declaration.  This could be difficult to resolve since different
formats will certainly have diverse means of identifying their
data encodings.

A workaround I have used is to strip out the first line of a
gml file I know has western european characters and replace it
with an xml declaration for ISO-8859-1, using head, sed etc or other
non-xml parsing utility.
