Modifying my WP-SynHighlight addon for WordPress I came across a problem, that WordPress rewrites symbols inside my codesyntax shortcode with their nicer Unicode equivalents. I patched code against some. Then against some more. And then some more… And at last I felt tired of patching my code. Suddenly, I came across no_texturize_shortcodes filter, documentation for which at the time of written was published nowhere.
