When a title of a page is in LTR characters, it may be displayed incorrectly, because the punctuation will jump to the wrong end of the line. For proper display on the page itself it can be solved by using something like [[Template:Correct title]], but when the title is listed in a category, this template has no effect. So, for example, the title of [[Help!]] is displayed in categories in the Hebrew Wikipedia as "!Help". See the Beatles albums category.
Adding LRM in the end of the title would solve this problem; a redirect from a title without the LRM could be created for easy linking. LRM is not allowed in page titles, however; see Bug 3696.
