should have escaped hyphen as it could be used for ranging.
sorry for the bother...

Subject: Regular Expression : Bad Character Range
Date: Thu, 19 Dec 2013 23:50:52 -0300
Hey guys,
I'm trying to compile a regular Expression while encountering the following
issue, any hints ?
is hyphen "-" or underscore "_" considered any meta character which is not
allowed when putting into the range ?
Thanks
Frank
