5.4.8 Other text concerns

• References should occur at the end of a sentence; for more information see the Texinfo manual. Ideally this should also be the final sentence of a paragraph, but this is not required. Any link in a doc section must be duplicated in the @morerefs section at the bottom.
• Introducing examples should be done with

  . (i.e., finish the previous sentence/paragraph)
  : (i.e., 'in this example:')
  , (i.e., 'may add foo with the blah construct,')
  

  The method “sentence runs directly into the example” is discouraged.

• Write abbreviation and acronyms in uppercase letters, e.g., HTML, DVI, MIDI.
• Colon usage
  1. To introduce lists.
  2. When beginning a quote: “So, he said,...”.

     This usage is rarer. Americans often just use a comma.

  3. When adding a defining example at the end of a sentence.
• Non-ASCII characters should be directly used; this is, don’t say ‘Ba@ss{}tuba’ but ‘Baßtuba’. This ensures that all such characters appear in all output formats. There are limitations for PDF output, though, because the used fonts only support a relatively small number of Unicode characters.⁶
