You need to decode the incoming text as strings is encoded to map the wide range of characters used worldwide.you can customize the ItemTemplate of AttachmentEditor Control and make a value converter that decodes the incoming string as the following:
public class StringDecoder : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
string decodedValue= System.Convert.ToString(value);
return HttpUtility.UrlDecode(decodedValue);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
#endregion
}then you should embed it into your XAML file:xmlns:converter="clr-namespace:[Your App Namespace]"
Add the converter to your resources <Grid.Resources>
<converter:StringDecoder x:Key="EncodingConverter" />
</Grid.Resources>
and set your new Item Template (this is same as default) with the converters: <esri:AttachmentEditor.ItemTemplate>
