@vonosmas Thank you so much for the feedback so far on this PR. I have resolved most comments and have pushed out the new changes, please let me know if the changes look good and I will rebase and clean up commit history. Also please let me know if you want me to remove the temp variable from wide char tests entirely or keep it for few subtests?
