This book contains, in a few quotes from monumental inscriptions, some special characters that may not be available in all fonts. There are instances of the letters i, u, and o with macrons and u with breve. These have been rendered using the HTML entities for the Unicode characters: i, u, o, and u respectively. There are also single instances of the letters m and x with macron and two instances of letter n with macron. As there are no Unicode characters for these, they have been rendered as [=m], [=x] and [=n].
