SEO vs. Unicode After a major load of 404 with some category and tag URL, I questioned on StackOverflow about my WordPress blog. My blog is in Unicode Bānglā. After a nice anatomy on the fact in Facebook1 with some CodeGeeks, we came to a solution for both 404 on Unicode characters and SEO for Unicode sites.

Mr. Sarim Khan (the Gittu) suggested a nice solution for a URL:

  • For category: http://www.example.com/category/astronomy/জ্যোতির্বিজ্ঞান‌‌‌‌‌‌‌‌‌
  • For posts: http://www.example.com/%postid%/আমার-পোস্টটি-যে-বিষয়ে

For this case the article will browse with the preceding category /astronomy, and will work for English SEO too. And the rest of the section /bānglā-slug would work for Bānglā SEO, and with this method the 404 can be minimized to a great extent.

But for a nice URL with Bānglā contents, I can manage my post and page URL, when I'm writing my page or post. But for Bānglā tags, and categories, how can I achieve such a modified URL? How can I put a Bānglā and English tag/category (taxonomy) at a time?

Currently I'm following http://domain/%postname%. How can I rewrite my URL, so that I can achieve such a benefit of lesser 404 for Unicode URL, and also doesn't get down in SEO chase.

Desired URL is:

And of course: Is that really possible?

1. Facebook thread image: I'm afraid, most of the discussion was in Bānglā.

  • I am not sure I understand the problem. The 404s come from broken copy & paste or dumb crawlers. There isn’t much you can do about that. Adding a trailing slash will help a little bit. If you want an English slug for a Bangla Category, just edit the slug in the category manager.

  • @toscho http://www.prothom-alo.com/economy/article/55104/কোরবানির_পশুর_চামড়ার_দাম_নির্ধারণ‌ is a URL used by The Daily Prothom Alo - a popular Bangla Newspaper. It may be a different framework or CMS, I don't care, but it's recently done - I guess to make the site more SEO-friendly. Yes you are right I can put English slug by editing the Category/Tag, but what about posts? If I activate the %postname% permalink it activates a /postname for my post URL. How can I make it understand to put the post_id first and then with a slash my Bānglā slug. And when I'm writing a post, I'm... Oct 12, 2013 at 9:01
  • ...assigning it to a category or tag and the slug creates for it automatically. How can I make the WP understand that I want a path for the category like 'take the English slug first and then put a Bānglā slug there after? I have to edit categories and tags - I don't want it that way. If I want it be done automatically, then isn't it preferred? Oct 12, 2013 at 9:04

    "Do you want the Bangla and the English category names in the URL?" - exactly that what I need. And I want it by default with a click or code-tweak. Oct 12, 2013 at 9:10

    This would require a major rewrite of the existing add term metabox. Adding a slug field to the term edit pages and using that in an URL is simple. Writing a new metabox for that is rather time consuming.

If you write your post titles in Bānglā but set the post slug in English, you can do this:

 function wpse117090_pre_post_link( $permalink, $post ) {
    return str_replace( '%posttitle%', sanitize_title( $post->post_title ), $permalink );

 add_filter( 'pre_post_link', 'wpse117090_pre_post_link', 10, 2 );

Then change your permalink structure to, for example, /%postname%/%posttitle%/

(Please note that the above code doesn't make %posttitle% an actual queryable rewrite tag, it's just a simple string that gets replaced by the sanitized post title when the permalinks are created.)
