Translate phrases like 'Read more' in _uikit.php

[vleerk]

Hi,
I'm building a multilanguage site with blog functions in _uikit.php installed from Ryans site-regular.
The main translation is okay. I also have a Functional Field 'snips' in template 'snippets', and a page 'snippets' to create words and phrases. This works fine in any template with 

<?=$pages->get('/snippets/')->snips->flowers?>

But I just can't figure how to translate phrases like 'Read more' or 'Posted by' in _uikit.php 
I read a lot in this forum and tried several ways with no success, so I need your help here. 

function ukBlogPost(Page $page, $options = array()) {
	
	$defaults = array(
		'summarize' => null, // Display blog post summary rather than full post? (null=auto-detect)
		'metaIcon' => 'info',
		'moreIcon' => 'arrow-right',
		'moreText' => __('Read more'), 
		'categoryIcon' => 'hashtag',
		'bylineText' => __('Posted by %1$s on %2$s'), 
	);

	$options = _ukMergeOptions($defaults, $options);
	$title = $page->title;
	$date = $page->get('date|createdStr');
	$name = $page->createdUser->name; 
	$body = $page->get('body');
	$metaIcon = ukIcon($options['metaIcon']);
	$moreIcon = ukIcon($options['moreIcon']);
	$categoryIcon = ukIcon($options['categoryIcon']);
	$n = $page->get('comments')->count();
	$numComments = $n ? "<a href='$page->url#comments'>" . ukIcon('comments') . " $n</a>" : "";
	
	if($options['summarize'] === null) {
		// auto-detect: summarize if current page is not the same as the blog post
		$options['summarize'] = page()->id != $page->id;
	}
	
	$categories = $page->get('categories')->each($categoryIcon . 
		"<a class='uk-button uk-button-text' href='{url}'>{title}</a> "
	);

	if($options['summarize']) {
		// link to post in title, and use just the first paragraph in teaser mode
		$title = "<a href='$page->url'>$title</a>";
		$body = explode('</p>', $body); 
		$body = reset($body) . ' ';
		$body .= "<a href='$page->url'>$options[moreText] $moreIcon</a></p>";
		$class = 'blog-post-summary';
	} else {
		$class = 'blog-post-full';
	}

	if($options['summarize']) {
		$heading = "<h2 class='uk-margin-remove'>$title</h2>";
	} else {
		$heading = "<h1 class='uk-article-title uk-margin-remove'>$title</h1>";
	}
	
	$byline = sprintf($options['bylineText'], $name, $date); 
	
	// return the blog post article markup
	return "
		<article class='uk-article blog-post $class'>
			$heading
			<p class='uk-margin-small'>
				<span class='uk-article-meta'>
					$metaIcon
					$byline
				</span>
				<span class='categories'>
					$categories
				</span>
				<span class='num-comments uk-margin-small-left uk-text-muted'>
					$numComments
				</span>
			</p>
			$body
		</article>
		<hr>
	";
