Is there an error in get_the_tag_list()?

Question

I'm using the theme TwentyThriteen1.0 for my WordPress blog.

I recognized that the tags in the meta-part of an article are not separated by a comma. I had a look at the function twentythirteen_entry_meta() in the file functions.php of my theme, which contains:

$tag_list = get_the_tag_list( '', __( ', ', 'twentythirteen' ) );

According to the documentation for get_the_tag_list() (http://codex.wordpress.org/Function_Reference/get_the_tag_list), the tags should be separated by a space after the comma. Looking at the HTML source reveals </a>,<a href=, instead of </a>, <a href=.

When I now add a space in the functions.php in front of the comma:

$tag_list = get_the_tag_list( '', __( ' , ', 'twentythirteen' ) );

the HTML source has both spaces: </a> , <a href=. This is really strange to me,... Is this a error or deliberate?

Or is this an error of the function translate() (alias __()) that removes trailing spaces if there are no leading spaces? I'm using the german version of Wordpress.

Answer 1

There is a possibility, that this string has been already translated and WP is displaying the translation, which has another format.

Try to pass a comma without a function, or take look at _x, where you can specify the context, you are translating.

EDIT

/**
 * Function fixes unknown issue of an unusual space in the tag list
 * @param string $html a piece of html code
 * @ return string
 */
function fix_tags_separator_bug($html){
    $separator = ", ";
    return preg_replace("/(\s){0,},(\s){0,1}/", $separator, $html);
}
add_filter("the_tags", "fix_tags_separator_bug");
