From 4d92af5ace491a2e87a6c73e5afa9ed53ac86bd0 Mon Sep 17 00:00:00 2001 From: Ryan Harrison Date: Tue, 28 Aug 2018 20:22:32 +0000 Subject: Handle non-printing characters at beginning of extraction region Currently if a text extraction region begins on a non-printing character then "" will be returned. This is the incorrect behaviour, instead the call should scan ahead until a printing character is found and start extracting from there. Also proactively adds a similar check and scan for the end of the extraction region.
