hyphenation in

Fixed in 3.2.4.

Sorry, still seeing ­s unless <h1> and <h2> are excluded …

What version of Catch Box are you using? I’m a bit stumped here. I could reproduce the problem with Twenty Fourteen, but not with Catch Box (which does not trigger the wp_title filter at all in its current release, although I’ve not found any code in it that messes with wp_title).

Catch Box 4.3.6 (which should be the latest and greatest version). Catch Box sets add_theme_support( 'title-tag' ).

Just tried to understand the code. As far as I can see, WP_Typography::process_title() is registered as a filter for any type of title. As I can prove using some debug code, it is called for <title>. WP_Typography::process_title() calls WP_Typography::process(), which calls PHP_Typography::process(). Within PHP_Typography::process(), there is nothing which stops process_words() from being called for the content of <title>. Consequently, the content of <title> is hyphenated.

The functionality to exclude <h1> and <h2> in order to exclude <title> is mentioned in the readme and the changelog – looks like that has been an issue long time ago …

I’ve researched the issue a bit and there has been a change in how titles are handled in WordPress 4.4. Previously, the filter wp_title was used – that’s what I handle in wp-Typography 3.2.4.

Since WP 4.4, that filter is not triggered anymore. Instead, there is a new filter document_title_parts. wp-Typography currently does NOT touch that filter and in my minimal test environment, WP_Typography::process() is not called for themes with `add_theme_support( ‘title-tag’ ) – that’s why I could not reproduce this at first.

The various filter hooks called *title (starting in https://github.com/mundschenk-at/wp-typography/blob/ed9d8deb8fa78c76189759115fd44261b71c0739/includes/class-wp-typography.php#L224) refer to post titles (i.e. <h1>), not to the <title> tag.

I′ve added an echo ("<!-- PHP_Typography:process('" . $html . "') -->"); right after the first if-statement in PHP_Typography:process() and I can see the comment right before <title> in the generated HTML code.

Adding a debug_print_backtrace() proves that it comes from WP_Typography->process_title.

To be exact, it comes from apply_filters(single_post_title) which you hook in class-wp-typography.php.

Thanks, that has put me on the right track. This stems from wp_get_document_title using the various title template tags to populate the <title> tag when not on the front page.

There actually was a bug in PHP_Typography that prevented Hyphenate headings from working correctly ($is_title was not passed on to process_words), but I think I’ll also create a special filter for document_title_parts that strips out any or zero-width space characters that may have crept in.

Please have a look at version 3.2.5.

Got a whitescreen issue on the blog front page. Had to disable the plugin.

Actually, pages and posts do work. Only the front page is broken.

Pages and posts look pretty good: <title> isn′t hyphenated any more and the “hyphenate headings” setting seems to do what it is supposed to do. Only titles passed to other plugins (in my case: Add Metatags) are still hyphenated.

The autoloading issue is fixed in 3.2.6. Can’t do much about how other plugins use template tags (you might want to have the contents of the single_post_title hyphenated if used as <h1>).

Perfect :-). Thanks a lot for your help – and thanks a lot for this great plugin!

By the way: You might want to get rid of that if-statement referring to the exclusion of <h1> and <h2> at the very beginning of PHP_Typography::process(). After today′s fixes, these lines of code seem to be some sort of a “leftover” from an (outdated) workaround, aren′t they?

Thanks again for your help :-).
