[Plugin: rootsPersona] File names skip accentuated letters

Hi,
Again, thanks for this wonderful plugin !
I would like to report 2 difficulties to manage the persona / files names.
1 – A person called “Paul Henry NAME” will have his page named “Paul HenryNAME” (without space between “Henry” and “NAME”). One would prefer “Paul Henry NAME” instead, easier to read.
2 – Accentuated letters are very common here in France (é, è, ç, …), but they are skipped when creating the person page : “Jérémie NAME” becomes “JrmieNAME” which is not that nice ! I understand that accentuated letters are not suitable for file names, maybe turning them to non accentuated letters would be a first step (like Jeremie NAME) ?
