[mapguide-users] Legend and runtime Layer filter

[Kenneth Skovhede, GEOGRAF A/S]

And you have not added the ? when saving?

A guess would be that the Xml has the UTF-8 BOM when you are saving it,
and the loading code does not accept it, and inserts a placeholder for a 
non-printable char.

When you have the string in .Net and want to get the bytes, try to do this:
System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding(false, 
true);
byte[] bytes = encoder.GetBytes(layerDefXml);
Then pass the bytes when saving the layerdefinition.

I have created a special Xml serializer class to deal with this in the 
MaestroAPI:
http://svn.osgeo.org/mapguide/trunk/Tools/Maestro/MaestroAPI/Utf8XmlWriter.cs

>> Hi Kenneth,
