I am not the source of the data, but I can special case them one way
or the other.
However I am wondering about my use of [[:graph:]] to match characters
that have glyphs. I was not expecting there to be characters that have
glyphs to not be in the graph class. In the short term I might want to
change the way I am testing that.
I should also try the equivalent test in perl to see if it is more likely
tied to the unicode implementation on my system or if it appears to be
Postgres specific.
