Excerpt not displaying final punctuation mark.

I use manual excerpts and while it shows the entire text, it keeps chopping off the final punctuation mark. So I’ve had to hard-code a period mark in the theme.

Here’s something I would write in the excerpt block:

“This isn’t the first time he went there.”

But it shows this:

“This isn’t the first time he went there”

Here’s the two different codes I’ve tried:

<?php wpe_excerpt('blog_1', 'wpe_excerptmore'); ?>

<?php the_excerpt(); ?>

They both display the same thing. Any tips?
