Comment (by steevithak):

 Sounds good, I like the idea of consolidating the char list in one place
 as a define. I chose \s because it seemed to cover the most cases in the
 smallest space. However, in addition to 200B, I found this list of quasi-
 whitespace Unicode chars that are not recognized \s:

 newlines-perl

 Maybe an alternate/easier way is to consider a shortcode terminated
 character to be *any* character that's not legal for use in the shortcode
 name? Maybe something like ^\w (or whatever the appropriate list is if not
 \w)?
