The library rules for title case are even more complicated than that. I learned that you capitalize the first and last words, even if they ARE prepositions or articles. You're right in that the edge cases like apostrophes and multiple capitals (e.g., "McDonald's") are annoyingly complicated to get right.

For my website, I have a "turn filenames into titles" function. For example, a-sunrise-to-remember.jpg becomes "A Sunrise to Remember" which uses a small canned list of the most common prepositions and articles (including a few in Spanish). Every once in a while, I find I have to add yet another special case.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
