Typogrify.module brings the typographic refinements of Typogrify to Drupal.

Wraps ampersands (the “&” character) with <span class="amp"></span>.
Prevents single words from wrapping onto their own line using Shaun Inman's Widont technique.
Converts straight quotation marks "" to typographer's quotation marks “”, „“ or «» using SmartyPants language dependent.
Converts multiple hyphens to en dashes and em dashes (according to your preferences), using SmartyPants.
Wraps multiple capital letters with <span class="caps"></span>.
Wraps initial quotation marks with <span class="quo"></span> or <span class="dquo"></span>.
Adds a css style sheet that uses the <span> tags to substitute a showy ampersand in headlines, switch caps to small caps, and hang initial quotation marks.
Inserts ligatures (if supported by platform and browser).
Replaces ascii arrows with unicode arrows (if supported by platform and browser).
Inserts thin-space in abbreviations.
Groups digits in large numbers.
Replaces = in words with a soft hyphen (), to allow hyphenated line-breaks.

The original Typogrify is Python code by Christian Metts. Typogrify.module uses Hamish Macpherson's PHP port of that code, php-typogrify.

After updates: open all filter using typogrify, check the new features and save.
To avoid conflicts with other filter, typogrify should be the last in the filter-queue.

The 8.x-1.0 release is compatible with Drupal 8 and Drupal 9.
