在雄辩的访问器中修整（\\ xa0）后出现UTF-8错误

Question

I'm trimming the first_name and the last_name of my users on a Model via Eloquent Accessors with the next helper:

function clean($string){
    return trim($string, " \t\n\r\0\x0B\xc2\xa0");
}

Then in the model:

public function getFirstNameAttribute($firstname){
    return clean(ucwords(strtolower($firstname)));
}
public function getLastNameAttribute($lastname){
    return clean(ucwords(strtolower($lastname)));
}

A lot of names comes from an excel an has trailing spaces which can be removed trimming \\xa0, but the problem comes when it tries to trim special characters, as (à).

I tried removing it and it doesn't fail, but well, it doesn't remove the trailing spaces.

I also tried making sure that the headers charset were set to utf-8

Any idea? Thanks.

I just want the invisible spaces to be gone :/

The error message:

InvalidArgumentException in JsonResponse.php line 69:
Malformed UTF-8 characters, possibly incorrectly encoded

Try to use mb_strtolower() and mb_convert_case() instead of strtolower() and ucwords() .

Instead of trim() you could try this function from here :

function mb_trim($str) {
    return preg_replace("/(^\s+)|(\s+$)/us", "", $str); 
}
