Consulting Dictionary.com, I could find “publically” accepted by only one authority — WordNet®, whereas “rôle” is accepted by Dictionary.com Unabridged (v 1·1), The American Heritage® Dictionary of the English Language (Fourth Edition), the Kernerman English Multilingual Dictionary (wherein it is listed as the primary spelling), The American Heritage® Stedman’s Medical Dictionary, and Merriam–Webster’s Medical Dictionary; therefore, I don’t think that they’re comparable. Rôle is the original spelling, and remains perfectly standard to this day. Diacritical and other supra-ASCII spellings are often omitted in typed text, but that can in a great many (perhaps the majority of) situations be explained by the effort that must be invested in order to insert the necessary character(s) using a basic keyboard. Whether you believe, as I, , and  do, that the rôle spelling ought to be retained, or you believe, as  and  do, that the role spelling ought to be used instead, I’m sure we can all agree that consistency is necessary; the word role occurs once later in the article — I’m going to change it to rôle. Whether role or rôle is chosen, both ought to match.
