This is rather puzzling. What are you describing as a "unicode
semicolon"? Possibilities include:

(a) U+003B SEMICOLON (which is exactly what you need)
(b) U+037E GREEK QUESTION MARK (which looks like (a))
(c) U+061B ARABIC SEMICOLON (which looks like (a) rotated 180 degrees)

How did you get it into your source file?

What was in your
# coding: ?????
or similar line at the top of your source file?
