In Scribus, the hebrew sequence Vav+Shuruq(05D5+05BC) doesn't render properly.
I used the Cardo FONT ecause it is a free UNICODE font but the same appens with other UNICODE hebrew font.

Please compare the PNG files and notice the dot position on the 6th gliph (starting from the left).
It renders correctly in MS Word while in scribus, it is off, on the right of the vav (the straight character looking like a stick).

For reference on the names and aspect of the hebrew character, you can refer to:
