Setting list item field values with Chinese text

I am using CSOM to create list items. It works perfectly except for Asian languages. I am reading in a file with UTF-8 encoding and specifying UTF-8 when I read it in. When debugging the app, the characters look correct in the ListItem.FieldValues property before I call the Update and ExecuteQuery.

The field values show garbled when I view the list item properties in SharePoint. It looks like there is an encoding issue.

Is there anyway to specify the encoding when I add the list item?

Thanks for any info,

Bill
