I display the photo title on the desktop with the <wp-title> tag.

On files with non-ASCII characters in the title those characters come through on the screen as "??". At the moment I'm using Calibri as the display font, so I know the characters in question are available in the font.

For example the file called "Møns Klint chalk cliffs at dawn, Møn Island, Denmark" is displayed as in the attachment.

And files with titles in non-Roman scripts -- Hindi, Japanese, Chinese, etc. -- come through entirely as question marks.

Any thoughts?
