In The Unicode Standard Version 3.0, the Latin small letters d l and t with caron (U+010F, U+013E, U+0165) are actually shown with a trailing apostrophe (d', l', t'). On each character there is the following note:
the form using apostrophe is preferred in typesetting However, the Latin capital letter L with caron (U+013D) is shown with an apostrophe (L') but no note. The Latin capital letters D and T with caron (U+010E, U+0164) show proper carons and notes that the preferred form is with a caron (hacek).
