CI_Typography::format_characters()

format_characters($str)

This method is similar to auto_typography() above, except that it only does character conversion:

• Quotes are converted to correctly facing curly quote entities, except those that appear within tags.
• Apostrophes are converted to curly apostrophe entities.
• Double dashes (either like – this or like–this) are converted to em—dashes.
• Three consecutive periods either preceding or following a word are converted to ellipsis (…).
• Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.

Usage example:

$string = $this->typography->format_characters($string);
