Character codes 128 to 159 (U+0080 to U+009F) are not allowed in HTML; even if they were, they would likely be unprintable control characters. Tidy assumed you wanted to refer to a character with the same byte value in the specified encoding and replaced that reference with the Unicode equivalent. You are recommended to use CSS to specify the font and properties such as its size and color. This will reduce the size of HTML files and make them easier to maintain compared with using elements.
