If the shortcode produces a lot of HTML then ob_start can be used to capture output and convert it to a string as follows:

Register widget in functions.php

 
// =========================================================================
// REGISTER NEW WIDGET
// =========================================================================
function custom_widgets_init() {

    register_sidebar( array(
            'name' => 'Custom Widget',
            'id' => 'custom-widget-id',
            'before_widget' => '<div class="custom-widget">',
            'after_widget' => '</div>',
            'before_title' => '<h4 class="custom-title">',
            'after_title' => '</h4>',
        ) );

}
add_action( 'widgets_init', 'custom_widgets_init' ); 

Place this code where you want to appear the widget

<?php dynamic_sidebar('Custom Widget'); ?> 

<?php
function wpf_filter_gettext( $translated, $original, $domain ) {
    if ( $translated == "OLD_TEXT" ) { $translated = "NEW_TEXT"; }
return $translated;
}
add_filter( 'gettext', 'wpf_filter_gettext', 10, 3 );

Remove translation

function remove_translation( $translated_text, $untranslated_text, $domain ) {

$removable_text = 'Ide kerül az eltávolítani kívánt kifejezés.';

if ($untranslated_text === $removable_text ) {
return '';
}

return $translated_text;
}
