The ‘no_texturize_tags‘ filter allows you to specify which HTML elements should not run through the wptexturize() function.
By default, WordPress will automatically texturize all post/page content. The texturize process replaces “normal” quotes with “fancy” quotes (aka “smart” quotes or “curly” quotes). Sometimes this is NOT what you want… particularly if your shortcode must contain raw, preprocessed text.
Example Migrated from Codex:
Add the blockquote HTML tag to tags exempt from texurization.
