Use of character sets like EBCDIC, RISC-OS-Latin1, Windows-1252 and Big5 (which are not completely code-by-code equivalent) is strongly discouraged.
Period leading thereby becomes the province of the setting engine and not corrupted by the designer of the font in use.
Corollary to recommendation 3.
Decimal points are typically placed in the middle of the vertical space occupied by numbers.
Web pages are allowed to use underlining to indicate links, but consider using a style sheet where colour is used to indicate links for visually able persons. Use a dark colour like blue for links unless this would render the text illegible given the chosen background colour.
Technical manuals sometimes benefit from sparing use of bold face to deliberately draw attention to salient points, such as the definition of a piece of terminology, or a reference to a menu item or window title. Consider using a monospaced or sans-serif font for this purpose instead, however.
By convention, capitals are used to designate model numbers, ASCII character names, Unicode character names, BBC BASIC keywords, programming language constants etc. as well as important passages of legal text. You may also consider using correct casing for legal text, perhaps adjusting the type size for emphasis of an important paragraph.
Do not capitalize the second or third words in a compound word which is important to the heading, unless the subword is otherwise important.
The first word of a heading must always be capitalized unless it would violate another recommendation or rule. Otherwise, fewer capitals in less important headings is acceptable typesetting practice to assist readability.
(Here the term "capitalize" and its derivatives should be taken to imply title casing only, not the capitalization of all letters in a word. Indeed, this practice is discouraged by previous recommendations.)
