patchdiff: improve scaling of filenames in diffstat to handle UTF-8 chars

The goal of this patch is to improve how UTF-8 characters are handled when generating a diffstat. Details are provided in the commit message of the patch itself.

In this cover letter I would like to ask if this patch (if it gets accepted, obv) can be considered a valid GSoC "microproject".

Also, as this is my first contribution to Git, please let me know if I made any mistakes!
