[Plugin: Cyr-To-Lat] Bug with slugs containing trailing non-alphanumerics

When post’s slug contains some non-alphanumeric characters at the beginning or the end – they’re converted to multiple dashes. Example -> 20” are converted into 20–.

Here is the fix:

add the next code to line 38:

$title = preg_replace('/\-+/', '-', $title);
$title = preg_replace('/^-+/', '', $title);
$title = preg_replace('/-+$/', '', $title);
