[Bulgarian Language Pack lacks transliteration] Flexicontent URL in latin

Hello friends,
my Flexicontent articles are in cirylic and my URL's look like:
mysite.com/16-2016-apr-12-06-51-20/17-2016-apr-12-07-28-04

How can i make URL's look like:
mysite.com/article-title-in-latin/categori-title-in-latin

I enclose picture

Hello

i have added transliteration, see here:

czech, croatian, greek, french, russian, etc
(code from PHOCA International alias plugin for J1.5)
- it was not updated for J3.x because Joomla language packages were supposed to include this ?? , but they never DID (yet ?)

NOTE: code will be triggered if you do not enable Joomla global option "UNICDE aliases"

can you provide an 1 to 1 character map for Bulgarian like done here:

github.com/FLEXIcontent/flexicontent-cck...b4eeca22e587eb44R677

then URLs will be:
.../445-cat-alias-latin/3455-item-alias-latin

if you enable unicode then you can have bulgarian text in the URL

ok done please see below.
What do i must do next ?

+ // BULGARIAN
+ if ($this->language == 'bg-BG') {
+ $bgLangFrom = array('А', 'а', 'Б', 'б', 'В', 'в', 'Г', 'г', 'Д', 'д', 'Е', 'е', 'Ж', 'ж', 'З', 'з', 'И', 'и', 'Й', 'й', 'К', 'к', 'Л', 'л', 'М', 'м', 'Н', 'н', 'О', 'о', 'П', 'п', 'Р', 'р', 'С', 'с', 'Т', 'т', 'У', 'у', 'Ф', 'ф', 'Х', 'х', 'Ц', 'ц', 'Ч', 'ч', 'Ш', 'ш', 'Щ', 'щ', 'Ъ', 'ъ', 'Ьо', 'ьо', 'Ю', 'ю', 'Я', 'я');
+ $bgLangTo = array('A', 'a', 'B', 'b', 'V', 'v', 'G', 'g', 'D', 'd', 'E', 'e', 'Zh', 'zh', 'Z', 'z', 'I', 'i', 'J', 'j', 'K', 'k', 'L', 'l', 'M', 'm', 'N', 'n', 'O', 'o', 'P', 'p', 'R', 'r', 'S', 's', 'T', 't', 'U', 'u', 'F', 'f', 'H', 'h', 'C', 'c', 'Ch', 'ch', 'Sh', 'sh', 'Sht', 'sht', 'Y', 'y', 'Io', 'io', 'Ju', 'ju', 'Ja', 'ja');
+ $langFrom = array_merge ($langFrom, $bgLangFrom);
+ $langTo = array_merge ($langTo, $bgLangTo);

Hello

added,

you can now visit v3.0.x-stable branch:
github.com/FLEXIcontent/flexicontent-cck/tree/3.0.x-stable

click "Download ZIP" and install in a development / testing site

- then edit an item , let the alias be empty and then click save
- not for category edit form you will need to set the alias manually to appropriate latin characters

Hi,
i downloaded the file but I do not know how to install it and where to install it.
Please help

just install it like an extension in joomla
