Miss a "space" in google search result

Hi, I have a little problem
when I try to search my blog in google
site:www.enterpr1se.info

I found some blog title had missed a space, like
abc| my blog
But when I open the blog, I see “abc | my blog” in the title, when I open the source code, it is “abc | my blog”
Why Google search result missed a space?
Is there anything I can do?
Thanks
