Slug doesn't revert locale correctly

[Jenselme]

Expected and Actual Behavior

I am using Slug.php to generate slugs in a phalcon project. The project is configured to display the dates in French. However, after I generate a slug, the dates are in English. If I don't create a slug, the dates are in French as expected.

I expect the date to be always in French.

Locale value (from setlocale(LC_ALL, '0');):

LC_CTYPE=C;LC_NUMERIC=C;LC_TIME=fr_FR.utf8;LC_COLLATE=C;LC_MONETARY=C;LC_MESSAGES=C;LC_PAPER=C;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;LC_IDENTIFICATION=C

I use the Slug like this:

$slug = SlugGenerator::generate($str);

Sample controller:

<?php

namespace Controllers;

use Phalcon\Utils\Slug;

class TestController extends Base\ViewController
{
    public function indexAction()
    {
        $this->view->setVars(['slug' => Slug::generate('à moi')]);
    }
}

Sample view

<div class="row page-content sale">
    {{ slug }}

    <div class="date">
        <span class="day-string">{{ strftime("%a", strtotime('2017-10-22T08:00:00.000Z')) }}</span>
        <span class="day">{{ strftime("%d", strtotime('2017-10-22T08:00:00.000Z')) }}</span>
        <span class="month">{{ strftime("%b", strtotime('2017-10-22T08:00:00.000Z')) }}</span>
    </div>
</div>

I was able to track the error to this line: if I comment it, the locales are correctly restaure. Is the operation it does really required?
