Option to respect original casing and encoding

[rjalexa]

I am amazed by the power and usefulness of this library, but Is there a way to respect the original casing? Example:
database: Hervé Le Corre->nominally->Name: herve familyname: le corre
while I'd love to have:
database: Hervé Le Corre->nominally->Name: Herve familyname: Le Corre
in my language for example there are many family names similar to "De Petris" or "de Iuliis" where the "de" particle originally meant "from the family of", and its casing also carries information since generally speaking the lower case "de" was found in aristocratic families only.
Please also note that in the above example Hervé is a grave accented letter e and I would need to preserve these.
Other examples in my sample which could be troublesome:
database: De Petris->nominally->Name: de Lastname: petris
This wrongly assumes that the lastname prefix De is a first name.
Carlos Ruiz Zafón->nominally->Name: carlos ruiz Lastname: zafon
Here Ruiz gets wrongly processed as a middle name and the accented ó gets demoted to a normal o
Marcos Ordóñez->nominally->Name: marcos Lastname: ordonez
Here the n loses its tilde.
