Checking code you've posted and they are not mentioned here.
$chars = array( "А"=>"a","Б"=>"b","В"=>"v","Г"=>"g", "Д"=>"d","Е"=>"e","Ж"=>"z","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"=>"h","Ц"=>"c","Ч"=>"ch", "Ш"=>"sh","Щ"=>"w","Ъ"=>"","Ы"=>"i","Ь"=>"", "Э"=>"e","Ю"=>"ju","Я"=>"ja","а"=>"a","б"=>"b", "в"=>"v","г"=>"g","д"=>"d","е"=>"e", "ё"=>"e","ж"=>"z", "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"=>"h", "ц"=>"c","ч"=>"ch","ш"=>"sh","щ"=>"w","ъ"=>"y", "ы"=>"i","ь"=>"","э"=>"e","ю"=>"ju","я"=>"ja", " "=> "-", "."=> "", "/"=> "-", "-" => "-");

Code: [Select]

$chars = array( "А"=>"a","Б"=>"b","В"=>"v","Г"=>"g", "Д"=>"d","Е"=>"e","Ж"=>"z","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"=>"h","Ц"=>"c","Ч"=>"ch", "Ш"=>"sh","Щ"=>"w","Ъ"=>"","Ы"=>"i","Ь"=>"", "Э"=>"e","Ю"=>"ju","Я"=>"ja","а"=>"a","б"=>"b", "в"=>"v","г"=>"g","д"=>"d","е"=>"e", "ё"=>"e","ж"=>"z", "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"=>"h", "ц"=>"c","ч"=>"ch","ш"=>"sh","щ"=>"w","ъ"=>"y", "ы"=>"i","ь"=>"","э"=>"e","ю"=>"ju","я"=>"ja", " "=> "-", "."=> "", "/"=> "-", "-" => "-");

ѓ , љ , њ, € ... etc

those wrong chars are in the last osclass ver 4.4.0,  inside in file formatting.php

@Ivanko
I still do not understand, what is wrong on € ?

@Ivanko

The chars what you use in formatting.php for ru-ru  are not existing in ru alphabet.
Please replace chars with what i have provided.

ѓ , љ , њ, € ... etc
Those chars above are not exist, it is more looks as ehieroglyphs))

There are many miss matches

 $cyr = array('а','б','в','г','д','ѓ','е','ж','з','ѕ','и','ј','к','л','љ','м','н','њ','о','п','р','с','т','ќ','у','ф','х','ц','ч','џ','ш','А','Б','В','Г','Д','Ѓ','Е','Ж','З','Ѕ','И','Ј','К','Л','Љ','М','Н','Њ','О','П','Р','С','Т','Ќ','У','Ф','Х','Ц','Ч','Џ','Ш','€')

In red ink are not existing letters in RU alphabet

Also you have 31 chars, must be 33, 2 letters are gone )

@Ivanko
We are not trying to do cyrilic for Russia only/or/separately.

Then you can include all 53 letters Slavic and not 31
€ - this also not part of cyrilic)

@Ivanko
There does not make sense to be strict what is and what is not cyrilic, but what may be in URL and what should not be there
I think having € sign is not good as well.

This is a key - missed letters in last osclass core not making correct url...

Let me know if you plan to fix it ?

Or I can proved full translite and you can add it in next update, so we can fix the bug.

@ivanko
Please only provide new letters and their mapping.

$str = "А а Б б В в Г г Ґ ґ Д д Ђ ђ Е е Ё ё Ж ж З з З́ з́ И и Й й Ѝ ѝ І і Ї ї Ј ј К к Л л Љ љ М м Н н Њ њ О о Ō ō П п Р р С с С́ с́ Т т Ћ ћ Ќ ќ У у Ӯ ӯ Ў ў Ф ф Х х Ц ц Ч ч Џ џ Ш ш Щ щ Ъ ъ Ы ы Ь ь Э э Ю ю Я я";

97 elements without zero )

space is separator.

@Ivanko
Please send it in one of format used by osclass right now.

@Ivanko
Thank you, are you sure these signs should be in URL ?
'##','#','\'\'','\'',
Does not look correct for me.

@Ivanko

'##','#','\'\'','\'',

Hi it is correct

## - capital letter
# - small letter
'' - capital letter ( backslash is php separator)
' - small letter (same here backslash as php separator)

here is also an example of general translit
https://translit.net/


as array should looks like below
$str = "А а Б б В в Г г Ґ ґ Д д Ђ ђ Е е Ё ё Ж ж З з З́ з́ И и Й й Ѝ ѝ І і Ї ї Ј ј К к Л л Љ љ М м Н н Њ њ О о Ō ō П п Р р С с С́ с́ Т т Ћ ћ Ќ ќ У у Ӯ ӯ Ў ў Ф ф Х х Ц ц Ч ч Џ џ Ш ш Щ щ Ъ ъ Ы ы Ь ь Э э Ю ю Я я";
$str = preg_replace('#\s+#',',',trim($str));
$myArray = explode(',', $str);

$map ="A a B b V v G g Gj gj D d Dz dz E e Jo jo Zh zh Z z Z z I i J j J j J j J j J j K k L l Lj lj M m N n Nj nj O o O o P p R r S s S s T t T t Kj kj U u U u U u F f H h C c Ch ch Dzh dzh Sh sh Shh shh ## # Y y '' ' Je je Ju ju Ja ja";
$map= preg_replace('#\s+#',',',trim($map));
$myArray2 = explode(',', $map);


by the way, you can add in the end this letter є and map je , this letter existing in Ukrainian alphabet
