There was an error that occurred when text was copied from Microsoft Word into an entry and the text contained an apostrophe. Word uses special angled apostrophes that look more pleasing to the eye. In fact, they do the same with quotation marks. They use special characters for quotation marks so that they angle in towards the text they surround.
Anyway, these special characters are actually different than the plain text apostrophes and quotation marks and they really messed up the database script for inserting/editing entries. This has now been fixed (the special characters get replaced with their plain text counterparts before they get pushed into the database). Enjoy.
