Text of Quran

I don't know much about English language but i try to learn.Can anyone tell me what is the exact meaning of 'Generally accepted' in the following text:

"The recension of Uthman had been handed down to us unaltered. So
carefully, indeed, has it been preserved, that there are no variations of
importance -- we might almost say no variations at all -- among the
innumerable copies of the Quran scattered throughout the vast bounds of
the empire of Islam. Contending and embittered factions, taking their rise
in the murder of Uthman himself within a quarter of a century from the
death of Muhammad, have ever since rent the Muhammadan world. Yet
but ONE QURAN has been generally accepted amongst them; and the
consentaneous use by them all in every age up to the present day of the
same Scripture, is an irrefutable proof that we have now before us the
very text prepared by command of the unfortunate Caliph. There is
probably in the world no other work which has remained twelve
centuries with so pure a text."

please help me....
