Not working category (tags) in Russian

[sim2github]

Seems like strtolower not work with UTF-8. Last rule cut off capitalized letters.
mb_strtolower works:

function createSlug($text)
{
  $dict = [
    //Russian translit
    'а' => 'a',
    'б' => 'b',
    'в' => 'v',
    'г' => 'g',
    'д' => 'd',
    'ж' => 'zh',
    'з' => 'z',
    'и' => 'i',
    'й' => 'j',
    'е' => 'e',
    'ё' => 'yo',
    'о' => 'o',
    'п' => 'p',
    'р' => 'r',
    'к' => 'k',
    'л' => 'l',
    'м' => 'm',
    'н' => 'n',
    'т' => 't',
    'ч' => 'ch',
    'с' => 's',
    'ц' => 'c',
    'у' => 'u',
    'ф' => 'f',
    'х' => 'h',
    'ш' => 'sh',
    'щ' => 'shch',
    'э' => 'eh',
    'ю' => 'yu',
    'я' => 'ya',
    'ы' => 'y',
    'ь' => '',
    //Ukrainian additional symbols
    'і' => 'i',
    'є' => 'ye',
    'ї' => 'yi',
    //Some of the special characters
    ':' => '-',
    ';' => '-',
    '.' => '-',
    ',' => '-',
    ' ' => '-',
    '\'' => ''
  ];

  $text = strtr(mb_strtolower(str_limit(trim($text), 255, ''), 'UTF-8'), $dict);
  $text = iconv('utf-8', 'ascii//translit', $text);
  return preg_replace('#[^a-z0-9\-]#si', '', $text);
}

@klocus according to the documentation setlocale must be set relative to the value of language (like ["en_english"=>"en_US", "pl_polski" => "pl_PL", ... ]), for 2bytes UTF-8 symbols languages (like Russian, maybe Turkish, Indonesian) need transliteration by dictionary.
So createSlug must have second parameter for LC_ALL set and extend dictionary for supported languages.

Tested:

• English
• Polish
• French
• Turkish
• Swedish
• Russian
• Italian
• Spanish
• Dutch
• Indonesian

[sim2github]

My changes brake compatibility for Polish language at least. So we need cooperate with contributors to fix this issue for supported language and maybe examine with native speakers that`s all works fine.

If you dont plan use not tested languages - patch function manually till problem not fixed. Im not core developer, so i will wait till @klocus say what to do.

Iconv with hardcoded pl_PL locale in createSlug function don't return translited symbols.

function createSlug($text)

My propose:

function createSlug($text)
{
  $dict = [
    //Russian translit
    'а' => 'a',
    'б' => 'b',
    'в' => 'v',
    'г' => 'g',
    'д' => 'd',
    'ж' => 'zh',
    'з' => 'z',
    'и' => 'i',
    'й' => 'j',
    'е' => 'e',
    'ё' => 'yo',
    'о' => 'o',
    'п' => 'p',
    'р' => 'r',
    'к' => 'k',
    'л' => 'l',
    'м' => 'm',
    'н' => 'n',
    'т' => 't',
    'ч' => 'ch',
    'с' => 's',
    'ц' => 'c',
    'у' => 'u',
    'ф' => 'f',
    'х' => 'h',
    'ш' => 'sh',
    'щ' => 'shch',
    'э' => 'eh',
    'ю' => 'yu',
    'я' => 'ya',
    'ы' => 'y',
    'ь' => '',
    //Ukrainian additional symbols
    'і' => 'i',
    'є' => 'ye',
    'ї' => 'yi',
    //Some of the special characters
    ':' => '-',
    ';' => '-',
    '.' => '-',
    ',' => '-',
    ' ' => '-',
    '\'' => ''
  ];

  $text = strtr(strtolower(str_limit(trim($text), 255, '')), $dict);
  $text = iconv('utf-8', 'ascii//translit', $text);
  return preg_replace('#[^a-z0-9\-]#si', '', $text);
}

Greek transliteration also have problems...

[KonstantinFromRussia]

Thank you.
But the decision is not complete.
Now the problem with the tags in Russian, written with a Capital letter.
For example:
tags - тег1 тег2 тег3 - normally saved when editing a post
tags - Тег1 Тег2 Тег3 - not saved
I write a post, add one tag - Пост1, but I can’t add Пост2 tag, when post is saved, Пост1 tag remains.
Tag written with a capital letter - there can be only one !!!

[KonstantinFromRussia]

Sorry
The problem with the tags in Russian with a capital letter was in the original version.

Yes, and there is a problem with transcription of slug too.
In the English version, the slug is set automatically.
In the Russian version, the slug must be set manually.

[KonstantinFromRussia]

Understood!
It should be like this:

function createSlug($text)
{
  $dict = [
    //Russian translit
    'а' => 'a',
    'б' => 'b',
    'в' => 'v',
    'г' => 'g',
    'д' => 'd',
    'ж' => 'zh',
    'з' => 'z',
    'и' => 'i',
    'й' => 'j',
    'е' => 'e',
    'ё' => 'yo',
    'о' => 'o',
    'п' => 'p',
    'р' => 'r',
    'к' => 'k',
    'л' => 'l',
    'м' => 'm',
    'н' => 'n',
    'т' => 't',
    'ч' => 'ch',
    'с' => 's',
    'ц' => 'c',
    'у' => 'u',
    'ф' => 'f',
    'х' => 'h',
    'ш' => 'sh',
    'щ' => 'shch',
    'э' => 'eh',
    'ю' => 'yu',
    'я' => 'ya',
    'ы' => 'y',
    'ь' => '',
    'А' => 'A',
    'Б' => 'B',
    'В' => 'V',
    'Г' => 'G',
    'Д' => 'D',
    'Ж' => 'Zh',
    'З' => 'Z',
    'И' => 'I',
    'Й' => 'J',
    'Е' => 'E',
    'Ё' => 'Yo',
    'О' => 'O',
    'П' => 'P',
    'Р' => 'R',
    'К' => 'K',
    'Л' => 'L',
    'М' => 'M',
    'Н' => 'N',
    'Т' => 'T',
    'Ч' => 'Ch',
    'С' => 'S',
    'Ц' => 'C',
    'У' => 'U',
    'Ф' => 'F',
    'Х' => 'H',
    'Ш' => 'Sh',
    'Щ' => 'Shch',
    'Э' => 'Eh',
    'Ю' => 'Yu',
    'Я' => 'Ya',
    'Ы' => 'Y',
    'Ь' => '',
    //Ukrainian additional symbols
    'і' => 'i',
    'є' => 'ye',
    'ї' => 'yi',
    //Some of the special characters
    ':' => '-',
    ';' => '-',
    '.' => '-',
    ',' => '-',
    ' ' => '-',
    '\'' => ''
  ];

  $text = strtr(strtolower(str_limit(trim($text), 255, '')), $dict);
  $text = iconv('utf-8', 'ascii//translit', $text);
  return preg_replace('#[^a-z0-9\-]#si', '', $text);
}

In this version, both tags and slugs work!

sim2github - Here, now everything works fine!
Thank you!

[KonstantinFromRussia]

sim2github - How to apply it in practice?
What should the correct code look like?

[klocus]

I will fix it soon.

[michu2k]

It won't be fixed in this Bf version, but we will look into this problem in future updates.
