Title of article in English wikipedia 

This morning, a wikipedian moved this page to a version including the full Vietnamese diacritics.  I just moved it back to the version without diacritics, for the following reasons:
 this is the English-language article about Ngo; and the great majority of English text written about Ngo (and other Vietnamese generally) do not include diacritics.  In English, in fact, inclusion of the diacritics is of no effect (at best) or even confusing because they have no effect on pronunciation in standard English orthography.  (Please note I am by no means an English-language bigot: I am a student of the Vietnamese language, and understand the fundamental role diacritic marks fulfill in correctly differentiating phonemes in Vietnamese.  However, it is clear that in English, the diacritics play no role in pronunciation.)
 The Wikipedia guidelines on naming conventions asserts that the most commonly used spelling in English is the form that should be used.
