About the Glyphs
The glyphs from the book can actually be directly transcripted into the Latin Alphabet -- letter per letter, glyph per glyph. It is a majuscule script, having only capital symbols. For example, the Latin letter E maps to a symbol homogeneous with Λ (capital lambda).

After observing these characters, it is possible to translate sections of glyphs that the game does not automatically translate, such as the text on summon tablets and the text on the red book seen in the menu screen. This particular book has some glyphs on its cover and inside has the three save slots. The title of this book is "Golden Sun", written in glyphs. The text in the magical symbol found on the top screen of the D.S. is also written in these glyphs, but is a transliteration of a foreign language, not English.
