Italic bullet sign of bulleted paragraph (with last italic characters) is exported like an equal sign with a line through it.
Workaround: Make all italic bullets non-italic. The following code achieves that:
RadDocument document = this.radRichTextBox.Document;
foreach (var paragraph in document.EnumerateChildrenOfType<Paragraph>())
{
if (paragraph.ListId != Paragraph.ListIdProperty.DefaultValue)
{
DocumentList documentList = document.ListManager.GetDocumentListById(paragraph.ListId);
int levelIndex = paragraph.ListLevel != Paragraph.ListLevelProperty.DefaultValue ? paragraph.ListLevel : 0;
if (documentList.ActualStyle.Levels[levelIndex].NumberingFormat == ListNumberingFormat.Bullet)
{
documentList.ActualStyle.Levels[levelIndex].SpanProperties.FontStyle = FontStyles.Normal;
}
}
}
this.radRichTextBox.UpdateEditorLayout();
