Replacement of letters of the Russian and Ukrainian alphabet

Hello. In the /administrator/components/com_dropfiles/helpers/files.php file, after about line 500 you have a character substitution. Please add Russian language:

'А' => 'a', 'а' => 'a',
'Б' => 'b', 'б' => 'b',
'В' => 'v', 'В' => 'v',
'Г' => 'g', 'г' => 'g',
'Д' => 'd', 'д' => 'd',
'Е' => 'e', 'е' => 'e',
'Ё' => 'yo', 'ё' => 'yo',
'Ж' => 'zh', 'ж' => 'zh',
'З' => 'z', 'з' => 'z',
'И' => 'i', 'и' => 'i',
'Й' => 'j', 'й' => 'j',
'К' => 'k', 'к' => 'k',
'Л' => 'l', 'л' => 'l',
'М' => 'm', 'м' => 'm',
'Н' => 'n', 'н' => 'n',
'О' => 'o', 'о' => 'o',
'П' => 'p', 'п' => 'p',
'Р' => 'r', 'р' => 'r',
'С' => 's', 'с' => 's',
'Т' => 't', 'т' => 't',
'У' => 'u', 'у' => 'u',
'Ф' => 'f', 'ф' => 'f',
'Х' => 'x', 'х' => 'x',
'Ц' => 'cz', 'ц' => 'cz',
'Ч' => 'ch', 'ч' => 'ch',
'Ш' => 'sh', 'ш' => 'sh',
'Щ' => 'shh', 'щ' => 'shh',
'Ъ' => '', 'ъ' => '',
'Ы' => 'y', 'ы' => 'y',
'Ь' => '', 'ь' => '',
'Э' => 'e', 'э' => 'e',
'Ю' => 'yu', 'ю' => 'yu',
'Я' => 'ya', 'я' => 'ya',

Basically I used GOST 7.79-2000(B) https://en.wikipedia.org/wiki/Romanization_of_Russian

Please also add the Ukrainian language (these are differences compared to Russian):

'Ґ' => 'g', 'ґ' => 'g',
'Є' => 'ie', 'є' => 'ie',
'І' => 'i', 'і' => 'i',
'Ї' => 'i', 'ї' => 'i',

Basically I used LC without diacritics https://en.wikipedia.org/wiki/Romanization_of_Russian

For myself, I also used the replacement of all uppercase letters of English with lowercase. I think that this is better for the formation of legal URL addresses.

'A' => 'a',
'B' => 'b',
'C' => 'c',
'D' => 'd',
'E' => 'e',
'F' => 'f',
'G' => 'g',
'H' => 'h',
'I' => 'i',
'J' => 'j',
'K' => 'k',
'L' => 'l',
'M' => 'm',
'N' => 'n',
'O' => 'o',
'P' => 'p',
'Q' => 'q',
'R' => 'r',
'S' => 's',
'T' => 't',
'U' => 'u',
'V' => 'v',
'W' => 'w',
'X' => 'x',
'Y' => 'y',
'Z' => 'z'

Thanks in advance.
