Every space has a dash and an extra space

[Squidious]

When I open an epub file in fbreader there is a 50/50 chance it will display every space as a dash and two spaces instead. For example, this sentence:

"Mickey was pale and silent."

Appears as:

"Mickey- was- pale- and- silent.- "

If I cut and past the text, it pastes just fine. So it appears to be a problem in the rendering?

Other readers view the file just fine. And sometimes I can just close fbreader and then reopen it and it is fine. Other times, I open it over and over and it always displays the symptoms.
