How to let Chinese characters show in URI when using eloquent-sluggable?

I am facing the same problem...Looking for solution...

Since most of us are not familiar with Chinese or the eloquent-sluggable package, Can you show what you have done so far, what is it that is not working and what is that you expect, local(e)isation can be tricky.

The problem with that package, and many other packages, is that they expect single-byte characters. Chinese characters, however, are multi-byte and normal php string manipulation functions do not work with them. I just had a glance at that package and its filled with multi-byte incompatible functions. You have two options I guess: build your own slug logic, or fork that repo and see if you can get it to work with multi-byte characters.

I tried a walk around approach, and it could work well so far. In "sluggable.php", set the "method" as follows:

function ($string, $separator) {

        //if the input string is in Chinese characters, return the original string
        $slug = (mb_strlen($string, "Big5") == strlen($string)) ?
            $slug = strtolower(preg_replace('/[^A-Za-z0-9]+/i', $separator, $string)) :
            $string;

        return $slug;
    }

If the input string, which should be slugged, is in Chinese characters, just return the original string. Otherwise, use the default conversion mechanism.

Thanks to zachleigh for a good piece of advice. The hint helps a lot.

I realize this is an old question, but maybe some still need help with it.

In multi-lingual projects, separate rulesets are often necessary for each supported language in order to avoid conflicts, but that also means that any non-default languages will need to be 'enabled' before they will work.

The (cviebrock/eloquent-sluggable) package relies on another package (cocur/slugify) for its localization rulesets. So, you must ensure that Chinese is included in the 'active' rulesets to make it work the way you need it to work. Below is a link to the core Slugify class, which includes the default ruleset array near the top (before the constructor). It does not include 'Chinese'.

https://github.com/cocur/slugify/blob/main/src/Slugify.php

However, the package does include a Chinese language resource, which you can examine here:

https://github.com/cocur/slugify/tree/main/Resources/rules

So, in your model, add the following just below the sluggable method (and be sure to import both Sluggable & Slugify):

public function customizeSlugEngine(Slugify $engine, $attribute)
{
    $engine->activateRuleset('chinese');
    return $engine;
}

In 2024, that should be enough to get it working.
