System information:
MacOS 11.7.1
Alfred 5.0.6
PHP 7.3.29

Additional context
It seems that nothing is working as it should be.

[biati-digital]

That's weird, nothing on that part changed from 4.0.0 to 4.0.1, it's exactly the same code.

This seems related to @arvidbjorkstrom PR that was included in 4.0.0, a quick search shows:

Normalizer is part of the [intl extension](http://www.php.net/manual/en/book.intl.php). While it's built by default, that does not necessarily mean that the specific version of PHP that you are using has it installed or enabled by default.

But again you said that it worked in 4.0.0, can you confirm that? did you change your PHP installation?

[XOKP]

No, it isn't working in both versions 4.0.0 and 4.0.1. It used to work in 3.5.0 but stopped after updating to 4.0.0, and 4.0.1 didn't fix the issue.

[XOKP]

I have not made any changes to my PHP. The issue can be resolved by reverting back to version 3.5.0.

[biati-digital]

Oh sorry, i misread your issue, like i mentioned, the issue was introduced by a PR #93 , hopefully the author of that PR @arvidbjorkstrom can help us find a solution and if not possible i'll remove that function to fix the error.

In the meantime you can use 3.5.0 or install the latest version and remove that line, if you want to give it a go please follow this steps

1.- Open the workflow folder

2.- Inside that folder open the file alfred/Alfred.php and remove line 318
$clean = normalizer_normalize($clean);

Thanks a bunch for the quick help! Your detailed steps were helpful.

[arvidbjorkstrom]

Hello!

The reason for the call to normalize is to avoid non ascii characters not matching what looks like the same character. For instance "hästkrafter" (horsepower) not matching the seemingly same word because one ä is really made from a combination of two characters (¨ and a in this case).

I see three ways to fix this:

1. Write code to check if normalizer_normalize exists, and if it does use it, otherwise just let the language files not match making words with non ascii characters not match.
2. Write code to "normalize" just the special characters used in the language files.
3. Find an alternative to normalize_normalize that is included in more PHP installations.

[arvidbjorkstrom]

@biati-digital If you want to remove the removal of ñ and other Spanish characters and add them to the es_ES-keys.php file I also added normalization for those characters as well.

[akrabat]

FWiW, if you're missing normalizer_normalize, that means that your PHP installation doesn't have the intl extension installed/enabled.

Homebrew installations of PHP include it by default, but I don't know if other package managers do. If you are using Macports, you probably need sudo port install php81-intl or sudo port install php82-intl depending on your PHP version.

Thank's @arvidbjorkstrom for the PR. An update has been released, it should be possible to update directly from Alfred or you can download the latest update from the releases page
