I've recently prepared two books for the MobileRead library which were first published in the 1890s.

The text in both books did not capitalize the first words of sentences which followed exclamation or questions marks, though of course that is normally done in 2016 English. One example is:

'O sage! what are we to do?' which one would expect to see as 'O sage! What are we to do?'

Is there any consensus whether it is best to capitalize words after exclamation and questions marks even when the original does not? Or to leave the words as in the original?

One of the books features a 'magic ring' which the first time it is mentioned is called Pentarbë, with the e having an umlaut. Every other time it is mentioned it is called Pentarbè, with the e having a grave accent. Is there any consensus as to whether it is best to have the spelling consistent? Or leave the diacritic as is?

I should mention perhaps that I have checked both spellings and the lack of capitalization against the HathiTrust version.
