Correct responses sometimes invalid, punctuation possibly to blame

I have noticed that Protobowl will not accept a variety of correct answers for the question.
Examples I have spotted in the wild so far:

• Titles with typographic quotes sometimes reject exact matches that include the typographic quotes or that substitute in straight quotes (it usually accepts the answer if the quotes are removed altogether)
• Answers containing the Unicode character RIGHT SINGLE QUOTATION MARK for use as an apostrophe do not accept exact match answers that also contain the apostrophe.
• A question where the answer was "The Gilded Age: A Tale of To-day" (not in quotes) did not accept an exact match, but I think that hyphen is a regular ol' ASCII hyphen-minus
• A question where the answer was "The Death of Wolfe" (with quotes, but straight quotes) did not accept an exact match (also with straight quotes).
• A question where the answer was "UNESCO headquarters/building" (not in quotes) did not accept an exact match.
• If an answer contains a parenthetical or bracketed note, sometimes an exact answer including the parenthetical note will be rejected.

Sometimes these rejections result in a prompt, sometimes they're just considered incorrect. My original conjecture was that proto was fumbling unicode somewhere (#UnicodeProblems, amirite) but I no longer know what to think.

This is still a problem.
