Punctuation

Quotation Marks

Use `` for the left mark, and for the right.

Hyphens/Dashes

• Hyphens separate the parts of a compound word. Use a single '-', without spaces.
• Endashes separate the bounds of a range, usually numerics. Use two '-' characters, without spaces.
• Emdashes separate distinct thoughts. Use three '-' characters, without spaces.
• Minus signs are a mathematical entity. Use a single '-' in math mode.

Periods

To get correct spacing:

• Use ".\ " if the period does not end the sentence.
• Use "\@. " if the period ends the sentence, and follows a capital letter.

Ellipses

Use \ldots (or \cdots for line-centered dots).

• Don't use three periods (bad spacing) or the Unicode character '…' (HORIZONTAL ELLIPSIS, U+2026).
• What about \dots? fixme

Tildes

Generally, \textasciitilde{} is the way to go. In math mode, use \sim.

• When typesetting a url, the url and hyperref packages handle tildes properly.

Backslashes

Use \textbackslash{} to render a backslash in text.

Unicode

Basic LaTeX doesn't support UTF-8 beyond expanding macros based on lexical sequences. If this is intended, use the utf8 parameter to the inputenc package. XeTeX aims to be a fully Unicode-aware TeX engine.
