This bug appears when trying to embed a document that has a greek filename and viewing in Internet Explorer (9 and possibly older versions as well).
An example of this bug can be viewed here:
The above example post has has two pdf's embedded.
When viewed in Chrome or Firefox it displays correctly.
When viewed in Internet Explorer the Greek filename doesn't get decoded correctly and therefore doesn't display. The download link however below the embedded document is correct and works.
Any chance of looking at this??? (The target audience is not tech savvy and uses mainly IE)
