Actually, it depends on the font. In that particular font, the period is
a tiny circle - topologically identical to the o. (Bubblegum Crisis
DVDs, if you're interested.)

The software in question is gocr - I tracked it down after a suggested
get-SRT-from-VOBsub commandline on this mailing list turned out to
require it. It's much better than nothing, but still quite a pain.

What it needs is the ability to say both "yes, even though it looks like
just one contiguous block this part is actually a separate unit" and
"no, even though you think they're identical these two blocks mean
different things". This is, drifting from the topic.
