"The Book of Mormon, a work of scripture of the Latter Day Saint movement, describes itself as having a portion originally written in reformed Egyptian characters on plates of metal or "ore" by prophets living in the Western Hemisphere from perhaps as early as the 6th century BC until as late as the 5th century AD. Joseph Smith, the movement's founder, published the Book of Mormon in 1830 as a translation of these golden plates. Scholarly reference works on languages do not, however, acknowledge the existence of either a "reformed Egyptian" language or "reformed Egyptian" script as it has been described in Mormon belief. No archaeological, linguistic, or other evidence of the use of Egyptian writing in ancient America has been discovered."

Standard language references such as Peter T. Daniels and William Bright, eds., The World's Writing Systems (New York: Oxford University Press, 1996) (990 pages); David Crystal, The Cambridge Encyclopedia of Language (Cambridge University Press, 1997); and Roger D. Woodard, ed., The Cambridge Encyclopedia of the World's Ancient Languages (Cambridge University Press, 2004) (1162 pages) contain no reference to "reformed Egyptian." "Reformed Egyptian" is also ignored in Andrew Robinson, Lost Languages: The Enigma of the World's Undeciphered Scripts (New York: McGraw Hill, 2002), although it is mentioned in Stephen Williams, Fantastic Archaeology: The Wild Side of North American Prehistory (Philadelphia: University of Pennsylvania Press, 1991)."
MOREOVER:
"The Book of Mormon uses the term "reformed Egyptian" in only one verse, Mormon 9:32, which says that "the characters which are called among us the reformed Egyptian, [were] handed down and altered by us, according to our manner of speech" and that "none other people knoweth our language." The book also says that its first author, Nephi, used the "learning of the Jews and the language of the Egyptians" (1 Nephi 1:2) to write his record which constitutes the first two books of the Book of Mormon. The abridgment that the Book of Mormon says was prepared by Mormon and Moroni nearly a thousand years later in approximately 380 AD, containing most of the balance of the book, was written in "reformed Egyptian" because it took less space than Hebrew, which Hebrew had also been altered after the people left Jerusalem."

AND
"Standard language reference works contain no reference to "reformed Egyptian". No non-Mormon scholars acknowledge the existence of either a "reformed Egyptian" language or a "reformed Egyptian" script as it has been described in Mormon belief. For instance, in 1966, John A. Wilson, professor of Egyptology at the University of Chicago, wrote, "From time to time there are allegations that picture writing has been found in America . ... In no case has a professional Egyptologist been able to recognize these characters as Egyptian hieroglyphs. From our standpoint there is no such language as 'reformed Egyptian'."Anthropologist Michael D. Coe of Yale University, an expert in pre-Columbian Mesoamerican studies, has written, "Of all the peoples of the pre-Columbian New World, only the ancient Maya had a complete script." Fifteen examples of distinct writing systems have been identified in pre-Columbian Mesoamerica, many from a single inscription."
