Hello @jordihs, it seems to me that you are mixing concerns in these pull requests. Can you please open a pull request containing the commit for the UTF-8 issue and open a separate issue and pull request for the RevengStrategy enhancement? Also it would be good if you could provide a test that guards that this works so we don't inadvertently delete or change the implementation later.

I messed up with the pull requests, it seems. I intended each one to be specific to its issue. I'm sorry, I am not used to this kind of workflow. I'll try and do as you say when I get some time to do it.

Maybe just close them and create new ones... Try to limit yourself to one commit per pull request, that makes the review process easier too
The best thing is to create a topic branch (i.e. HBX-2014) in which you implement the UTF-8 issue and another branch (HBX-2015) for the reveng issue. Make sure both branches are branched off from the master branch and only contain the commit relevant to the issue. The rebase/merge will be done by me 😉

OK, will do. Thanks for the pointers.
