XamlReader and Umlauts

Question

I've got a xaml with a german umlaut (s. below) now when I try to parse it, I get an invalidchar error.

When I don't use an XamlParser Context it works. But I have to use it in order to set some type mappings

---

XAML:

<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:test="clr-namespace:BR.UI.Tests.Items;assembly=BR.UI.ViewLocator.Tests"
    mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300">
    <UserControl.DataContext>
        <test:SampleViewModel />
    </UserControl.DataContext>
    <Grid>
        <Label>ö</Label>
    </Grid>
</UserControl>

Code which parses it

 var context = new ParserContext();
 var result = System.Windows.Markup.XamlReader.Parse(xaml,context);

I can't find anything to set an encoding hint (which would be .net String UTF-16) what am I doing wrong?

I also tried to inject the encoding with an XmlParserContext.

    var xmlcontext = new XmlParserContext(null, null, null, XmlSpace.Preserve,
                                          Encoding.Unicode);

    var context = new ParserContext(xmlcontext);

But it didn't help :-(

What do I need to do? Is there some kind of XAML encoding?

Answer 1

Answering my own question hope that is ok.

What helped for me was using the

System.Windows.Markup.XamlReader.Load(stream,XamlParserContext)

Method.

s. http://msdn.microsoft.com/de-de/library/ms590388.aspx

This method seems to respect the encoding of the string variable.

I still don't understand why this doesn't work with the Static ParseMethod. But I hope this solution will help someone else to safe time :-)
