I have try this plugin and i have same problem. I have try it ALL ALL ALL before submit ticket.
Only one plugin make it works to no say “Unable to create user with an empty name”
This is plugin https://wordpress.org/plugins/restrict-usernames-emails-characters/
with this plugin allow user to register but username not import correct, showing username with symbol or with numbers. You can see Screenshot.
–
I have close all this plugins and i try this plugin https://el.wordpress.org/plugins/wp-facebook-login/
Register works well and greek charachters on username convert it in “Greeklish”
example: If Greek name Νίκος on username this plugin make it Nikos .
But this plugin not fully integrated with buddypress and all my community, for example, does not show the user activity Or when user login in website.

Hi,

There is a fix for wordpress to allow russian / ukrainian characters on username, if you will check to create a new user with russian you will cannot do that cuz the wordpress it not allow, please test the function and let me know

this it’s a old function that some users used in the past, just replace the characters with your specific greek ones
COPY CODE
```
function kleo_translate_special_chars($str){
    $tr = array(
        "А"=>"a", "Б"=>"b", "В"=>"v", "Г"=>"g", "Д"=>"d",
        "Е"=>"e", "Ё"=>"yo", "Ж"=>"zh", "З"=>"z", "И"=>"i",
        "Й"=>"j", "К"=>"k", "Л"=>"l", "М"=>"m", "Н"=>"n",
        "О"=>"o", "П"=>"p", "Р"=>"r", "С"=>"s", "Т"=>"t",
        "У"=>"u", "Ф"=>"f", "Х"=>"kh", "Ц"=>"ts", "Ч"=>"ch",
        "Ш"=>"sh", "Щ"=>"sch", "Ъ"=>"", "Ы"=>"y", "Ь"=>"",
        "Э"=>"e", "Ю"=>"yu", "Я"=>"ya", "а"=>"a", "б"=>"b",
        "в"=>"v", "г"=>"g", "д"=>"d", "е"=>"e", "ё"=>"yo",
        "ж"=>"zh", "з"=>"z", "и"=>"i", "й"=>"j", "к"=>"k",
        "л"=>"l", "м"=>"m", "н"=>"n", "о"=>"o", "п"=>"p",
        "р"=>"r", "с"=>"s", "т"=>"t", "у"=>"u", "ф"=>"f",
        "х"=>"kh", "ц"=>"ts", "ч"=>"ch", "ш"=>"sh", "щ"=>"sch",
        "ъ"=>"", "ы"=>"y", "ь"=>"", "э"=>"e", "ю"=>"yu",
        "я"=>"ya", " "=>"-", "."=>"", ","=>"", "/"=>"-",
        ":"=>"", ";"=>"","—"=>"", "–"=>"-"
    );
    return strtr($str, $tr);
}

function kleo_extra_validate_username($valid, $username){
    if( !$valid ){
        $sanitized = sanitize_user( $username, true );
        $valid = ( ! empty( $sanitized ) );
    }
    return $valid;
}
add_filter('validate_username', 'kleo_extra_validate_username', 10, 2);


function kleo_extra_sanitize_user($user, $raw_user, $strict) {
    $user = kleo_translate_special_chars($raw_user);
    return $user;
}
add_filter('sanitize_user', 'kleo_extra_sanitize_user', 10, 3);
```
It should work

Hi

Not sure why that maybe the wordpress cannot allow to have duplicated names or similar.

I think you will have to extend the snippets that i have provided to you to perform a check if the current user has same name as an existing one then to be added to database or similar, you can do this with help of a developer.
