I do not see anything conditional about the OPs spec: "remove all characters after the last period.". Do you?

The spec doesn't assert there will necessarily be a period, either. I think my assumption is better than your assumption.

Is that really a possibility? Cos if it is, it means perl's unicode handling must be even more broken than I thought.

How is "perl's [sic] unicode [sic] handling" broken?

AFAIK, Perl and PHP are the only programming languages that have a regular expression pattern to match true characters (i.e., graphemes) instead of only one to match code points. You just have to know it and use it.
