    placeView: Always set text direction to LTR for phone numbers
    
    Since phone numbers are typically displayed using
    international format (starting with a +) this
    seems to result in Pango laying out the text with
    an overall RTL direction in RTL languages, resulting
    in groups of digits (separated by spaces) being
    arranged RTL, while the digit groups internally
    correctly is rendered LTR. And since also eastern
    Arabic numerals are written left-to-right, just
    insert a LRM marker to ensure the direction within
    the text is LTR (setting the text direction of the
    entire label widget gives off alignment).
